This place is such a delightful treat. Not only is the Barrio Cafe in what some Phoenicians would called the actual barrio, but it's non-descript on the outside and purely magical within. Not terribly difficult you keep your eyes peeled, Barrio Cafe is one of the best Mexican restaurants in Arizona and is a must try for any Phoenix local.
You really can't go wrong with anything on their menu, although their seafood offerings are my least favorites. I am in love with their conchita pibil, which is their slow-roasted pork and they have the best made-at-the-table guacamole in all of Phoenix. Their food is the kind of special occasion dinner that you and all your guests will be savoring every morsel, but save room for one of their delectable desserts! I'm a fan of their flan, in particular.
Service is spot on and it's usually pretty packed, so come as early as you can or face a semi-long wait at the bar. Don't worry though, they've got great margaritas. This is the place Tempe's Mucho Gusto wished it could be some day. But it probably won't.
