Why it's hot: This seasonal floating oyster and rosé hub is still hot as ever, even though summer is officially over. Located aboard the historic F/V Sherman Zwicker, a boat docked off of Hudson River Park's Pier 25 in TriBeCa, restaurant vets Mark Firth and Adrien Gallo are behind the maritime-exhibit-meets-bar. Get there soon before this ship closes up for winter at the end of the month.
Must-drink: Sherman's cup: white wine, seasonal berries, lemon, lime, orange ($16).
Insider tip: Try small plates like fried squash blossoms, crudo and, of course, a variety of raw oysters.
