Tucson's coffee scene splits across at least six real pockets, Fourth Avenue, the University of Arizona campus, downtown Congress Street, the Mercado west of I 10, Midtown Campbell and the Catalina Foothills. Each one is its own street, not a single desert city page.

Tucson's coffee scene stands on its own, separate from Phoenix's much larger market and Tempe's ASU campus scene. Its real search poles are Fourth Avenue with the University of Arizona corridor, and the Mercado San Agustin west of Interstate 10.

Caffe Luce runs three separate Tucson rooms, near the University of Arizona, downtown on Congress Street, and in Midtown along Campbell Avenue, each named on Visit Tucson, Tucson Foodie and Roadtrippers guides to the city.
