The following is the e-mail response from Taco Cabana when asked which of their menu items are vegan:
Thank you for your interest in Taco Cabana!
I’ve attached to this email (in PDF format) a listing of our vegan items.
If you have any difficulties opening or reading it, please let me know, I can also fax or mail it to you.
Our regular flour Tortillas, Burrito Flour Tortillas (12″) and Crispy Flour Bowl do have l-cysteine.
The l-cysteine is from animal source
There is not a dedicated area for vegan preparation.
Please don’t hesitate to contact me if you should have any further questions.
