Casa Romero

Spice things up at this moodily lit Back Bay Mexican spot, which woos couples with bold-colored walls, tiled tables and authentic South of the Border cuisine. The signature puerco adobado en chipotle y naranja—tenderloin of pork marinated in oranges, tamarind and smoked chipotle peppers—and a tangy margarita should do the trick. In the summer, the serene back patio, decked with hanging plants, is an intimate, date-worthy retreat.
