I haven't been here in about a year, so I apologize if anything has changed. Last time I was there the vegan options were quite limited, and the guacamole has sour cream in it. Like, all of it. So, you can't get the sour cream. However, you can add either potatoes or sweet potatoes (I'm pretty sure for free) to any burrito, so that's totally awesome.
Cons: Sour cream in the guacamole, Took over 30 minutes for takeout
