Don't look for the sign—there isn't one at this clubby, see-and-be-seen River Oaks sorta-Tex-Mex favorite. Re-opened in its third incarnation in March 2007, Armando Palacios's eponymous eatery—fashioned after 1920s Mexico City—is consistently packed with friends and regulars who love the clean, simple signature fajitas, queso flameado (a cheese dip made with chorizo and served with flour tortillas), and fresh lime-juice margaritas. "It's like our version of New York's Waverly Inn," says the owner. The bar is always hopping, and not with the young and the restless, either. Reserve the private room in the back for your next air-kissing celebration.
