"Boojum has enhanced their vegan and vegetarian offerings since the last reviews. They now offer a vegan three bean chili filling and vegan sour cream. I often order a three bean chili burrito with extra guacamole, vegan sour cream, lettuce, and salsa verde. It may be a bit expensive, but it will keep you satisfied for the rest of the day. Update: Reduced to 3 stars in June 2022 due to the discontinuation of vegan sour cream. I have also experienced cross-contamination issues recently (cheese in the lettuce). Despite this, Boojum remains a reliable choice and adds more vegan options for Veganuary. (Review updated from April 17, 2020)"
