DOWNTOWN. The striking Omni Severin Hotel includes this impressive seafood establishment. Skilled Chef Lisa Jellison thoughtfully prepares the pioneering dishes that are on the menu. You will forget that you are in a hotel restaurant the minute you taste the rock shrimp and vegetable terrine, grilled tuna, or lobster Wellington. Dishes are presented in an artful manner by the professional staff. An extensive wine list and a dessert menu are also available to make your pleasant dining experience a flawless adventure. Business attire. Reservations recommended.

KEYSTONE CROSSING. Shrimp, stone crab claws, clams, and oysters. Depending on the season, these are the goodies you'll most likely encounter on Keystone's affordable menu. Good service and enjoyable atmosphere complement enticing menu selections, and seafood is packed on ice, keeping it extremely fresh. Landlubbers find a variety of poultry, meat, and salad selections to please their own tastes. The establishment has been an award-winner for its excellent wine list, upscale atmosphere, and overall quality since 1992.

The Oceanaire Room is a 50s kind of place in the best sense ­ comfortable booths, Tommy Dorsey music, relish trays, informed waiters and a bar with eight different kinds of oysters. The menu changes daily, and the preparation allows the fresh flavor to come through with both traditional seafood dishes and more intrepid endeavors. The service is exquisite, and the huge portions can be shared or served in a half order.
