The service here can be the worst, but I think the food is great. I'm pretty sensitive to cross contamination and I've never gotten sick here (I eat here about once a month).
The staff was very clear that although there was a gluten free menu, there was almost no chance there wouldn't be cross contamination. I was starving, so I took a chance, which I later seriously regretted. I won't be eating at Barrio again, but not a bad place for a margarita.
One star is too many. Awful, rude and ignorant service. Unwilling to listen to food needs
The restaurant was great. The menu was very gluten friendly. I would be back if I lived out in Minneapolis.
I found lots of GF options here, using fresh corn tortillas instead of flour. Food is good although pricey, but man do they make one helluva margarita. My only disappointment is that they make their own chips in a shared fryer, so no chips for me (I'll bring my own next time.) Their tableside guacamole is outstanding, and the bartender was happy to bring me some vegetables so I could enjoy it. In fact, when I ordered the guac I wasn't thinking about the cross-contamination issue with the chips, and the bartender was the one who brought it up, so he was very knowledgeable and was watching out for me--very appreciated!
