I found this place randomly and asked for a bean burrito with no dairy. I was very pleasantly surprised to be offered soy cheese and tofu sour cream- and I wasn't charged extra for it which kept the price very reasonable. There's three different vegetarian fillings, all of which can be made vegan and had on/in every option.
Staff were friendly and it's a pleasant little place. The burrito was tasty though might not stand out amongst the many other burritos available but for the vegan options it's beats everywhere else I've been.
