A perennial favorite in the dim sum category, Tropical -- surprise -- also serves a great din-din. Traditional dishes include Hong Kong-style roast pork flavored with five-spice and then roasted; seafood-spinach soup; and always crisp, always succulent Peking duck. But innovative items are equally reliable, if unusual -- flounder pan-fried with peppercorns and jalape?os and served with bananas marinated in rice wine, for example, offers interesting counterpoints of textures, as does cherry-plum chicken wrapped with diced water chestnuts and fresh bamboo in egg-white crêpes. A healthy wine list replete with floral Rieslings adds to the fine-dining effect, giving aficionados of all kinds reason to make Tropical an evening as well as morning destination.
