Santiago's on So. Sheridan Blvd. is the only place I go for burritos. You can order your burrito plain, with green chili on the inside, smothered or deluxe and pay only for the options you want. You also have three options of heat to choose from. Service is always fast and friendly whether you eat in or pick up a to-go order.
The worse part about Santiago's - they're not open on Sunday.
