There’s this restraunt about a block away called Maya that is a schmancy Latin place at night but during lunch has a mini-Maya in the bar that has much cheaper lunch food. They have some excellent burritos and for lunch I got a Chicken Mole burrito with refried beans. This is by far my favorite that they do, and it’s really great. Make sure to ask the guy for extra chips when you pick up your order. One of the best lunch deals in the SoMA/Rincon area.
