I'm very fond of the Todai chain, which started in So Cal and is slowly spreading...

An asian-seafood buffet, with roughly 50' of cold seafood & salads, 50' of freshly made sushi & sashimi (and chefs who will make rolls to order), 50' of hot dishes mixing asian and western influances (Lobster Thermidor & Peking Duck), and a small array of fresh fruits and pasteries for desert. The quality is top-notch and it's not the usual "too long on a steam table" food.
