Decibel Coffee Works runs two Tucson cafes in two very different parts of the city. The first sits at the MSA Annex, 267 S Avenida Del Convento Bldg 9, part of the Mercado San Agustin Annex development west of Interstate 10. The second, Sol Block, sits at 2631 E Broadway Blvd in Midtown, and Decibel marked its arrival with a simple announcement that the second location at Sol Block was now open.

Two locations, two very different parts of the city, and two genuinely different weekly schedules. It is worth walking through both on their own terms, because the MSA Annex and Sol Block do not run identical hours, and understanding the difference matters for anyone trying to plan a visit to either one. Tucson counts 543,348 residents in the 2023 American Community Survey, a city large enough that a Mercado visitor and a Broadway Boulevard commuter can go months without crossing paths, which makes it worth spelling out exactly what each Decibel location offers rather than assuming one description covers both.

The MSA Annex Patio

Decibel's Mercado room sits at the MSA Annex, 267 S Avenida Del Convento Bldg 9, part of the Mercado San Agustin Annex development west of Interstate 10. This room keeps a varied weekly schedule, open Monday and Tuesday from seven am to two pm, and Wednesday through Sunday from seven am to eight pm, according to the shop's own locations page.

That split schedule, shorter hours at the start of the week and much longer hours from Wednesday onward, tells you something about how this room is actually used. It suggests a patio setting built for both morning coffee and a longer evening stay later in the week, right in the middle of the Mercado's own mix of food vendors and gathering space.

The Mercado San Agustin itself sits west of Interstate 10, a development built around exactly this kind of mix of food and drink businesses sharing one gathering space, and Decibel's Annex room benefits directly from that setting. A patio pouring coffee inside a destination people are already visiting for other reasons, other vendors, other food, an open courtyard, has a genuinely different customer flow than a standalone coffee counter has to build entirely on its own.

Sol Block on Broadway

Decibel's second room, Sol Block, sits at 2631 E Broadway Blvd, a Midtown Tucson address along one of the city's longer commercial corridors. Sol Block keeps a simpler, consistent schedule, open every day from seven am to two pm, according to the shop's own locations page, a straightforward morning through early afternoon window seven days a week.

That consistency is its own kind of statement. Where the MSA Annex location varies its hours across the week to accommodate both a shorter early week schedule and a longer late week evening stretch, Sol Block runs the exact same window every single day, a dependable choice for a Broadway regular who wants to know exactly when the doors will be open without checking twice.

Two Rooms, Two Rhythms

Put the two schedules side by side and a clear picture emerges. The MSA Annex, inside a lively food and market destination, leans into longer evening hours later in the week when that setting draws the biggest crowds. Sol Block, along a Broadway commercial stretch, keeps a steady, predictable morning through early afternoon window every single day, a rhythm built around a different kind of regular.

Running two cafes with two different weekly rhythms, rather than copying one schedule across both locations, suggests a business paying close attention to what each specific neighborhood and setting actually needs, rather than applying one template to both addresses.

Next Door to the Mercado

The Annex cafe does not sit alone. The Mercado San Agustin itself holds Presta's original cafe at 100 S Avenida del Convento, a short walk from the Annex, and Barista del Barrio's Grande Avenue kitchen is a few minutes north in Barrio Hollywood. That makes the stretch west of Interstate 10 one of Tucson's real coffee pockets, a place where a morning can move between several independent cafes without ever getting back in the car.

For a visitor, that density changes what the Annex is for. A coffee at the MSA Annex can be the start of an afternoon at the Mercado's courtyards and vendors, and the Annex's long Wednesday through Sunday evening hours, open until eight pm, fit the way people use the Mercado, lingering into the evening rather than grabbing a cup and leaving.

A Second Location Worth Noting

Decibel marks the Sol Block opening directly in its own words, announcing that its second location at Sol Block was now open, a milestone worth recognizing on its own. Growing from a single Mercado cafe into a second Broadway location is a real expansion for an independent Tucson coffee business, and naming that growth clearly matters for anyone trying to follow how the business has grown.

Decibel's own announcement also notes that the business went through a rebrand along the way, arriving at the Decibel Coffee Works name it carries today. Whatever prompted that change, the business that came out of it is the two room company operating now, with one foot in the Mercado and one on Broadway Boulevard.

Two Broadway Streets Away From Each Other

Broadway Boulevard runs a long way across Tucson, and it is worth being clear that Decibel's Sol Block room, at 2631 E Broadway Blvd, is a Midtown address, distinct from other Broadway coffee stops that show up further toward downtown. Broadway alone is not a precise enough description of where a coffee shop sits in a city this spread out, and Sol Block's specific address is what tells a customer where to go.

That level of specificity matters for any Tucson coffee shop on a long commercial street like Broadway, where two businesses sharing the same street name might sit miles apart from each other, serving completely different neighborhoods and completely different regulars despite the shared address format.

Two Distinct Settings, One Name

Stepping back, Decibel's two locations offer a coffee drinker different settings to choose from depending on what they are looking for. The MSA Annex, inside a lively food and market destination, suits someone looking to linger, especially during its longer Wednesday through Sunday evening hours. Sol Block, along a Broadway commercial stretch, suits someone looking for a dependable morning stop at the exact same time every day of the week.

Both locations carry the same Decibel name, which means a regular can pick the Annex's evening atmosphere one day and Sol Block's reliable morning routine the next without ever leaving the business they already know. That kind of range inside one Tucson name is rarer than it sounds in a city this spread out.

What Two Rooms Say About Growth

Growing from one room at the MSA Annex into a second room at Sol Block represents a deliberate expansion, the kind of step a coffee business only takes once it has real confidence in its ability to run more than one location well. Opening a second room on the other side of the city, rather than a few blocks from the first, also means reaching a different set of Tucson regulars rather than splitting the same crowd between two doors.

A business that expands within its own city, rather than staying fixed at a single address indefinitely, is still actively building its own story. Decibel's two locations today represent one clear chapter of that growth, a two location presence spanning the Mercado and Broadway Boulevard.

Seeing Both Rooms in One Day

Because both locations open at seven in the morning, a drinker who wants to see the two sides of Decibel can do it in a single day, with one catch. Sol Block closes at two pm every day, so the Broadway location has to come first. The MSA Annex runs until eight pm from Wednesday through Sunday, which leaves the whole afternoon and early evening for the Mercado side of town, where the courtyards and vendors around the Annex give a second coffee somewhere to settle.

On a Monday or Tuesday the math changes. Both locations close at two pm on those days, so a morning at both means moving from Broadway to the Mercado before lunch rather than after it. That is the kind of detail a visitor only learns by reading both schedules side by side, and it is exactly why two cafes with two different weekly rhythms are worth describing one at a time instead of under a single set of hours.

A Patio Setting Inside a Food Destination

The MSA Annex room's setting inside the Mercado San Agustin Annex development gives it a different atmosphere from a standalone cafe, surrounded by other food vendors and open courtyard space rather than sitting on its own along a commercial strip. That kind of setting invites lingering, a coffee that turns into an afternoon spent exploring the wider Annex, rather than a quick stop on the way somewhere else.

Sol Block, along Broadway Boulevard, offers the opposite experience by design, a straightforward coffee stop built for a Midtown commuter's morning routine rather than an extended visit. Together, the two locations give Decibel a genuine range across Tucson's coffee experiences, from a leisurely Mercado afternoon to a quick, dependable Broadway morning.

Two Rooms Among Many Tucson Doors

Tucson has no shortage of coffee doors. Dutch Bros lists 16 Tucson locations on its own locator, and 7 Brew runs two Tucson stands, one on East Speedway Boulevard and one on East Tucson Marketplace Boulevard. Those drive through stands are built for speed and sameness, the identical cup at every window across the city.

Decibel's two cafes work the opposite way. Each one is shaped by its own block, a patio inside the Mercado San Agustin Annex with evening hours late in the week, and a steady seven to two cafe on Broadway in Midtown. For a drinker choosing between a drive through and a cafe with a sense of place, that difference is the whole point.

Two Rooms Worth Finding on Their Own Terms

A business running two locations with two different schedules deserves a page that lays both out clearly rather than blending them into one vague set of hours. A Mercado visitor looking for the MSA Annex and a Broadway commuter looking for Sol Block are searching for two different things, even though both are ultimately looking for Decibel Coffee Works.

Hillcane builds exactly that kind of clarity for coffee shops running more than one location, distinct pages that state each location's own hours and character rather than forcing two different locations into one generic listing.

Frequently Asked Questions

Where is Decibel's MSA Annex room?

Decibel's Mercado room is at the MSA Annex, 267 S Avenida Del Convento Bldg 9, part of the Mercado San Agustin Annex development west of Interstate 10. It sits a short walk from the Mercado's courtyards and vendors, and from Presta's original room at 100 S Avenida del Convento, which makes this corner of the west side one of Tucson's denser coffee pockets.

Where is the Sol Block location?

Sol Block is at 2631 E Broadway Blvd, a Midtown Tucson address in the 85716 zip code along one of the city's longer commercial corridors. It is several miles east of downtown, so it is a different Broadway stop from the coffee shops near the downtown end of the boulevard. Decibel itself announced Sol Block as its second location.

How many locations does Decibel run?

Two. The first is the MSA Annex cafe at 267 S Avenida Del Convento Bldg 9 in the Mercado San Agustin Annex, west of Interstate 10. The second is Sol Block at 2631 E Broadway Blvd in Midtown. Decibel's locations page lists both locations with their own hours, and no third Decibel location appears there.

What are the MSA Annex location's hours?

According to Decibel's own locations page, the MSA Annex location opens seven am to two pm on Monday and Tuesday, then stretches to seven am to eight pm Wednesday through Sunday. Those longer evening hours late in the week fit the Mercado San Agustin setting, where visitors tend to stay for the courtyards and food vendors well past the morning coffee rush.

What are Sol Block's hours?

Sol Block, at 2631 E Broadway Blvd, opens seven am to two pm every day of the week, according to Decibel's own locations page. That is the same seven hour window on Monday as on Saturday, a schedule built for Midtown regulars on Broadway Boulevard who want to know exactly when the doors open without checking twice before heading over.

Do the two locations keep the same schedule?

No. The MSA Annex varies its hours across the week, seven am to two pm on Monday and Tuesday and seven am to eight pm Wednesday through Sunday. Sol Block keeps the same seven am to two pm window all seven days. A drinker who wants coffee after two in the afternoon has one option, the Annex, and only from Wednesday on.

When did the Sol Block location open?

Decibel itself announced that its second location at Sol Block was now open, following the original MSA Annex room at the Mercado San Agustin. The Sol Block room at 2631 E Broadway Blvd is the newer of the two, and its arrival took the business from a single west side room to a presence on both sides of Tucson.

Is Sol Block the same as other coffee stops on Broadway?

No. Broadway Boulevard runs a long way across Tucson, and Sol Block's address, 2631 E Broadway Blvd in the 85716 zip code, puts it in Midtown, well east of the downtown end of the boulevard near Congress Street. On a street that long, the street number matters more than the street name for anyone trying to find the right room.

What is near the MSA Annex location?

The Mercado San Agustin, with its courtyards, market hall and food vendors, plus Presta's original room at 100 S Avenida del Convento and Barrio Hollywood a few minutes north, where Barista del Barrio sits at 1002 N Grande Ave. The whole pocket sits west of Interstate 10, apart from Fourth Avenue and the University of Arizona campus.
