(Update 12-21: They've changed their menu to have "Celiac friendly" and "Gluten friendly" options, marking what is free of cross contamination and what isn't! I come here weekly and haven't gotten sick once.)
Most of their tacos are or can be made GF! It's all marked on the menu clearly with a red GF symbol. The cashier knew exactly what to do when I said I have celiac and made a note of it for the cooks to change gloves and make sure everything was clean. I got a carne asada and a carnitas taco and they were SO flavorful and delicious and best of all I didn't get sick! The line was pretty long but it was a Saturday night, and even then they were pretty fast. I can't believe it took me so long to try this place but I'll definitely be back soon. *Be sure to tell them you have an allergy or celiac, otherwise they won't know to keep your food separate.
Another update: They've changed their menu back to just GF with no mention of celiac, but this is because it isn't certified They still take the same precautions and can make almost every taco GF!
