The chips are awesome. The salsa is great. The thai-chili tofu is amazing. The draft beer selection is impressive. Yes, the tacos are cold, but it has never bothered me or anyone I've brought with me.
I've logged the most hours at the Lakewood location since it's a short walk from my current place but in terms of food the original Tremont location and newer Gateway location are just as good.
One of the reasons I love Barrio so much is because I can eat for around the same price that a beer costs. It is easily one of my top 5 favorite restaurants in Cleveland.
