We once read that making too many decisions causes your brain to crave glucose. Though we're not sure about the science behind that supposed fact, we can tell you from firsthand experience that an especially stressful day of work always makes us crave a Carolina's tortilla. This no-frills restaurant has been a Valley institution since 1968, drawing a crowd of customers that ranges from downtown business types to college students from ASU's downtown campus. The tortillas alone are worth braving the un-air-conditioned dining room, particularly when they hold servings of red machaca or green chile. We're also big fans of the Oaxaca Special, which combines cheese, potatoes, beans, and excellent chorizo.
