I put authentic in quotes because food in Mexico (at least in rural areas) is pretty heavy on lard and meat. I haven't been back since going vegan, but I imagine it will be a challenge :-)

This place, however, was a very pleasant surprise. I love Mexican food and am pretty tired of Chipotle burritos. This little joint has a HUGE selection of vegan and vegetarian options, which they are clearly proud of (and should be). We went for breakfast and had some great Soy Chorizo & Potato burritos. I look forward to returning for lunch and trying out their Calabacitas and Soya Verde burritos. They also have a pretty good selection of grab-n-go burritos and tamales in the fridge and sell some of their burrito fillings by the gallon if you're throwing a party. Best vegan Mexican food I've had here yet.
