Zuni has all the trappings of a neighborhood joint: cheap drinks, guileless American food with Cajun, Mexican and Mediterranean accents, dark lighting, cozy booths and a friendly bar. Though you can eat here pre-theater, it's off the radar and doesn't have a frenzied scene. For post-theater noshes, it's also quiet and easygoing. On the menu are half a dozen big salads, lobster ravioli, pan-roasted steak au poivre and catfish in pumpkin-seed crust with butternut squash gratin. At the bar is kid food for adults, including chicken fingers and mozzarella sticks.
