Mexican restaurants are usually a no-no :<(

The taco and tortilla shells and chips may contain wheat flour and they may
be contaminated by being fried in contaminated oil, or by being prepared on
floured boards.  The enchillado sauces and taco seasonings also can contain
flour or barley malt.  Taco bell and other restaurants mix oats in their
ground beef.

It is easy to prepare gluten-free Mexican meals at home, and it seems like
that will be my best option.
