Barrio's tacos are the "revelations about life" type. Absolutely amazing food and it's unbelievably cheap (2-5$/taco).
The wait staff is fun and upbeat. Ticket times are pretty short and the food comes out a good temperature.
Selection is great especially for parties of mixed carnivores, veggie burglars, and vegans. Almost all of the tacos can be mixed and matched to cater to specific diets or food allergies.
Definitely a regular place we love to go and will continue taking our out of town guests there as a "welcome to Cleveland's food scene."
Note: you can expect to wait a minimum of an hour and a half, however it is worth the wait and there is pretty much always a wait.
