I love Barrio tacos. I love how you can customize the tacos to whatever you could possibly want in a taco. Starting at $3 a taco, the bargain is hard to beat. It's so inexpensive but so good and filling.
Along with the tacos chips and salsa are complimentary. However I highly recommend the queso. It is such a big bowl. You can seriously eat several bowls of chips and it looks like you haven't put a dent in it. Really good for groups. I also love their margaritas. You can even mix the flavors together. And the rims are a perfect accompaniment when you can start to taste the tequila. You can get a sugar or salt rim. Sugar is my favorite. I also like to mix mango and guava flavors if you need a suggestion for a nice tropical drink.
The only downside to Barrio is that it's pretty small. So call ahead if you're coming with a group or even just two people. You're gonna wait a bit. But trust me the wait is definitely worth it. The food and service is phenomenal. Barrio is a great place for a good time with friends.
