When the lovesick duke in Shakespeare's Twelfth Night remarks, "If music be the food of love, play on," we'd like to imagine him at this late-night Mexican eatery inside Crescent Ballroom, downtown's most popular music venue, with burrito in hand. Loaded with ingredients like sweet al pastor marinated in achiote citrus, garlicky Angus beef braised with oregano, and tasty seasonal and local veggies, these massive beauties, wrapped in a thick, soft tortilla, will get you through your favorite band's riotous riff, bluesy ballad, or head-bobbin' jam — and with enough energy left for an encore.
