Long Island has hundreds of seafood restaurants, with a drift net's worth of shellfish and finfish. Here are three that provide a fine catch -- and some very good Greek fare, too.

Whole grilled fish is the hallmark of Trata, a summer place that also excels with Greek spreads, grilled octopus, grilled calamari, zucchini and eggplant chips, warm walnut cake and Greek yogurt. Standout Mediterranean swimmers: red fagri, a snapper; lavraki, a bass.
