Living in the neighborhood, I used to come to Barrio at least once a week. I didn't eat every time, though. I couldn't. I would ruin my taste for anything I made for myself at home.
The only issue I had with Barrio was the lack of space. I literally had to shout to get my voice over the roar of the crowd. Everything is packed so tight, I had to dodge waiters with trays and other customers coming and going while attempting to eat without turning myself into a cyclops with the fork.
When it's too crowded, I would often sedate myself with a tasty sangria from the bar. But heaven forfend if you'd like to sit there. Nope, there just happens to be at least 15 people packed into a 4' by 10' space, waiting for tables.
The food and drink is delicious, but I took away 1 star for feeling like I was in a NYC bar in downtown Phoenix.
