The breakfast burrito could be Colorado's official food. Just about every breakfast joint in Denver offers one, even if the only authentically Mexican thing about the place is the dishwasher. Vendors peddle breakfast burritos door-to-door at office buildings in the morning and sell them in LoDo at let-out. And you can find a good breakfast burrito on just about every block in the city — especially the 2500 block of Federal Boulevard. In this corner, at 2505 Federal, an outpost of Santiago's, the homegrown chain that's found many fans for its hot green chile and tidy, foil-wrapped breakfast burritos that go for $2 with cheese, $1.75 without (720-855-8109). Across the street, at 2524 Federal, Jack-n-Grill, Jack Martinez's shrine to New Mexican food, offers a very respectable Colorado breakfast burrito to-go for $2 (303-964-9544). And around the corner, at 2900 East 26th Avenue, Araujo (303-455-3866) wins the price game, burrito-filled hands down: Its breakfast burrito is just 99 cents. (Come back during the day for four tacos for $5.)
