Although burritos are the breakfast of champions in Denver, there are two camps on what constitutes a proper breakfast burrito. One side likes theirs on a plate, served huge and messy, slopped up with chile and requiring a fork. Then there are those who like them thin, manageable and ready to go. We fall solidly into this camp, but we also like surprises. And that's where Santiago's, a homegrown chain that seems to be taking over the world, comes in. Not only does Santiago's serve breakfast burritos every day, but it serves a different breakfast burrito every day: bacon one day, chorizo the next. No matter what's inside, the burritos are cheap, tidy and wrapped in foil, which means there's no reason not to order several and eat them on the run.
