Early-rising downtown workers and BART commuters know Tia Maria, tucked into the depths of Oakland City Center, for its generous breakfast burritos and steaming bagel egg sandwiches. The lunch crowd, meanwhile, finds solace from the hubbub of the upstairs plaza at the subterranean cafe where they line up to customize football-sized burritos, generous taco salads, or tortilla-less “cups” of rice, beans, and gauc. Enchiladas, tacos, and nachos round out the Mexican specialty choices, while soup and sandwich options Americanize the lineup. Tia Maria a welcome quick-serve Mexican-influenced alternative to the pizza, fast-food, and chain possibilities in the neighborhood. Serves breakfast and lunch Monday-Friday.
