This establishment is very close to my work and I often stop by to pick up a burrito for lunch. I strongly recommend placing your order by phone because come lunchtime this place gets quite crowded.
Being a chain restaurant, there are certain standardizations which I understand cannot be avoided. Still it is possible to customize your burrito to a great extent. I usually skip the rice and onions, substituting with few more vegetables instead. Their default level of spiciness is low so make sure you ask for spicy. The textured vegetable protein burrito is my favourite.
I like this location, certainly one of the better burrito places in town. The owner is very friendly too!
