Gluten-free review:
This place is known for their burritos but they also offer their burritos as tacos with corn tortillas, which is great for their gluten-free customers. I not only have a gluten intolerance but I'm also allergic to avocados (it sucks, I know) so I get my tacos without guacomole. My go-to is the rib-eye steak tacos with no guac, and their serving of steak is quite generous. Some of their tacos are not gluten-free though because of the soy sauce, so make sure you check with them first.
They're very accommodating to my allergies and pretty much know me by name now. I had one encounter where they forgot to omit the guac. I called in, came back and they replaced my tacos. Now whenever I go back they remember the incident and double and triple check to make sure there is no guac on my tacos.
The location is very small though (3 seats at the window) and they prepare everything in the same area, so if you have celiac's disease this won't be ideal due to potential cross-contamination. My sensitivity isn't very severe so I don't get a reaction from the tacos.
In terms of cost there is no price difference to get tacos instead of the burritos. Depending on whether you get a drink it's about $10-15 per person including tax.
Tip: Call ahead so you don't have to wait long. When they're really busy the wait can be 20 minutes.
