Agree with earlier post, servers are very knowledgeable and lots of options on the menu... paella is GF and I ordered the tuna y tuna app too. Their tortilla chips and anything fried go in a "shared" fryer so I opted to avoid any of those options (celiac). I didn't ask about tacos but they are in a corn tortilla so one would hope.
Barrio didn't have a separate GF menu or even notations on the regular menu but our server, Shayla, was very familiar with celiac and guided us through the menu. We felt safe ordering paella, corn on the cob, and the turkey mole special. All were delicious and I didn't have a reaction afterward. We'll be back!
