The words “fine dining” and “Dewey Beach” don’t typically jibe, but they do at Ponos Hawaiian Fine Dining. Owner Regan Derrickson scaled back a tad on the lavishness, but Ponos still delivers on fresh and inventive seafood, like the house special, macadamia-crusted opakapaka. New this season are fresh oysters and a build-your-own salad option.
