There’s no business like family business. Just ask the Versaces, the Jacksons, or the Weinsteins. Oh. And the Dentons. See, when Jason Denton opened his button-cute West Village haunt ‘ino (and later Lupa), his younger brother Joe was right by his side. Now Joe’s taking the stage as full-on partner at ‘inoteca, an offshoot of the original ‘ino, which opens today. Wine is still the name of the game at ‘inoteca, which has a selection of nearly 200 bottles and 25 wines by the glass or half carafe. Nibbles, courtesy of Chef and co-owner Kleinman, include the eminent truffled-egg toast, plus new items from paninis to piattis of melanzana lasagnette and frittata del giorno. Not to be missed: the salumi featuring culatello, a specialty of prosciutto crudo. With a space three times the size of ‘ino, a downstairs wine cellar, private dining, and outdoor seating, ‘inoteca might just upstage its older brother. Talk about sibling rivalry. ‘inoteca, 98 Rivington Street, at Ludlow Street (212-614-0473).
