New York clubs and chefs are clambering to the beach with new Hamptons outposts in time for Memorial Day weekend.

LDV Hospitality’s No. 8 will take over Saturday nights at Georgica in East Hampton. The spot also brought in chefs Greg Grossman, Matthew Fisher Redington and Kazuo Yoshida to redo its restaurant.

On Sunday, DKNY and DJ Hannah Bronfman will host an Ovarian Cancer Research Fund benefit where Bronfman will spin tunes. The bash takes the date once reserved for Jessica White’s Angel Wings Foundation gala, which is moving to Labor Day weekend.

At nearby Sienna Restaurant & Ultra­lounge, Donatella Arpaia is taking over the kitchen to serve her signature Italian dishes (“I’m famous for my meatballs, so I have to have those or customers yell,” she says) plus new creations with local, organic ingredients. She’s gotten input from her top-cardiac-surgeon hubby, Dr. Allan Stewart.

Over in Southampton, downtown pop-up party guru Travis Bass will host a Capri pool party with DJs and grub from BLT Steak.
