There are those days when nothing will satisfy your culinary cravings like oyster omakase. You know the feeling. Hey, when that mood hits, head for Hapa Sushi Lounge. Omakase, of course, means a multicourse chef's choice dinner (in Japanese). And at Hapa, depending on the bounty of the day, it can be an upscale orgy of mollusks exquisitely paired, if you like, with wine, sake, sparkling wine and champagne. Perhaps the selection will include a trio of Washington State oysters, served in-shell on a long sushi-style tray. Different varieties are presented hot, in a sauce of sake, soy, grape seed oil and chives; or cold as palate refreshers, in varying baths of ponzu, spicy daikon and green onion or lime and chile. Playing the perfect partner is wonderfully smooth Kurosawa Daiginjo sake. In this Valley's shell game, Hapa Sushi Lounge is a guaranteed winner.
