Trattoria al Forno and Big River Grille are the two sit-downs open at Boardwalk currently. Believe you can book the latter on OpenTable. Flying Fish and ESPN have yet to re-open. There are more sit-downs available across Crescent Lake at Yacht & Beach Club - Beaches & Cream, Cape May Cafe, Ale & Compass, Yachtsman Steakhouse, Crews Cup Lounge. And also several more at the Swan & Dolphin.
