We've had some innovative Floribbean and Pacific Rim concepts recently, but not many can hold on to their uniqueness over time. Not so Blue Sea, a tiny Asian seafood bar in the Delano that features communal seating and adventurous food you just don't see elsewhere -- not even on the menus of other sushi bars guilty of taking liberties with tradition. Like an appetizer of green tea noodles, crisped salmon skin, raw quail egg and spicy mayo; a maki roll of barbecued eel, mango, coconut, crabmeat and black sesame seeds; prosciutto and daikon sashimi; and an egg crèpe spiraled around shrimp, crab, Boursin cheese, Belgian endive, radicchio, and asparagus. All are fresh, deftly prepared, and delicious, with six dipping sauces to mix and match, including ponzu and peanut.
