Until hell freezes over, or Rio Nuevo ever becomes a reality, it's important to support downtown restaurants. While most of Tucson rolls up after 10 p.m., the Barrio bistro is just getting its buzz on. It's open for lunch and dinner, with an innovative menu that pleases everyone. We love the Jamaican jerk shrimp with orange jicama slaw and the Southwest antipasto platter, both of which come with four-star service. On cool days, the L-shaped patio attracts diners who like eating on the sidewalk. Intimacy reigns inside and out, whether it's at the bodacious bar or a comfortable booth.
