The two things that jettison my brain into a Barrio Cafe daydream are:
1) The Sangrita
2) The Churro dessert
In fact, if this place was called "Barrio Sangrita and Churro Shop", i would still want to run up to the building and give it a big hug.
Really, enough has been said here about the food, or atmosphere, or whatevs ... but if they're hoping to leave a legacy in Phoenix, its with these two items.
I prefer going to BC for brunch on Sunday. I enjoy that menu the best. Oh, and the table side Guac is a nice touch.
