Barrio is a great casual location for cheap, but delicious tacos. it is a unique custom order concept where you check off the items that you want to build your perfect taco. I think that it is the sauces that really make the tacos great. I recommend the cilantro lime aioli, it is my favorite but they have other great ones too. I also recommend the stoner queso, it is a little over priced, but is best to split with friends.
I love to go during happy hour. Tacos are $1 off making them $2 each and margaritas are half off making them $3 for house and $4 for a flavor. The only problem with happy hour is that it is almost always packed, especially during weekends. The deals are only in the bar area as well so you either have to wait longer or be lucky enough to grab a bar stool seat.
Overall its a great place with a fun, hip ambiance. The only reason I wouldnt give it a 5 is because its a little over rated. The tacos are good, but they are still just tacos.The wait is also sometimes a turn off for me since usually they have no good area to wait around in especially during the winter.
Definitely try it out, especially if you are not from Cleveland. All the Clevelanders love it!
