One of our favorite hangouts, Rosa Mexicano serves heavenly pomegranate margaritas ($8.50) and fresh guacamole ($12). For dinner, try Filete con Hongos ($26), a fillet smothered with wild mushroom-tequila cream sauce.
For smaller Mexican dishes and a wider range of flavors, head to Oyamel, chef José Andrés's newest restaurant. Order several dishes, and share them. Our favorites include tuna ceviche ($10), Vera Cruz-style red snapper ($10.50), and Tamales Verdes ($5.50). José's other eateries in Penn Quarter include Café Atlántico and minibar (Nuevo Latino), Zaytinya (Mediterranean), and Jaleo (Spanish).
