Highly sophisticated yet casual, this large space has a sleek wood-and-metal staircase, outsize red columns, curtained booths for privacy, and an open kitchen that turns out inspired French-Asian fusion fare. Consider wok-roasted mussels with lime, chili, and Thai basil; duck-filled imperial rolls; or stir-fried lamb with chilies. Desserts such as vanilla-yogurt panna cotta (a molded custard) with sesame-seed brittle and warm hazelnut-chocolate tart with Darjeeling-tea-scented ice cream continue the East-West theme.
