Tito's Burritos & Wings has several locations in the local area serving Mexican and Tex-Mex cuisine. Tito's is an MSG and peanut oil free restaurant. Cups, utensils, to-go bags and take-out containers are made from corn and recycled materials.
Gluten-free and vegan options are always available so please just ask. They list some suggestions on their website, which include Benno Burrito, Veggie Lovers Tacos, and Taco Salad (just replace the cheese with guacamole or black beans).
