I've always loved Qdoba over it's main competitor (both founded in Denver, 2 years apart). Seriously though, if the names were stripped from the building one would be hard pressed to name the place correctly.
All the ingredients are fresh and the prices are very reasonable. Heck we pay more at Taco Bell for vastly inferior product. The taco salad (~$9) is quite large and the number of options is huge. The knockout taco combo (3 for $9) is definitely worth the deal. So far my favorite has to be the two timer taco. I do wish that of the offerings there was a truly spicy one. Then again I eat ghost peppers, so that could be a me thing.
Parking lot is huge and easy to access on this always busy road. Bonus is the stop light. Store is very clean, the employees friendly.
