Jack Della Femina, son of Michael Della Femina and grandson of Jerry Della Femina, is opening his first Hamptons eatery, Bravo Toast, over July Fourth weekend, making him the third generation in the restaurant biz.

We hear that Bravo Toast will be a summerlong pop-up at the Cynthia Rowley store in Montauk. It’s near where advertising guru Jerry had his famous Della Femina firm and the Red Horse Market for years. A Bravo Toast “drive-thru” in LA will permanently open on Doheny Drive after the summer.

Jack learned the ropes from his dad, Michael, who owns the popular Croft Alley restaurants in LA.
