Nightlife isn't just happening below 23rd Street (remember when the borderline used to be below 14th Street?) as evidenced by the new restaurant/club Lavo from nightlife impresarios Noah Tepperberg and Rich Thomas, who also run Avenue, Marquee and Tao. So far LAVO, located on 58th and Park, has hosted two very different high-profile events. The first was a "soft opening" of the club which inhabits the old euro-spot Au Bar (but has been completely re-done) was hosted by Quest magazine (the preppy UES social bible) and a party for the website What2WearWhere which was founded by Karen Klopp to help busy chicks get their get-ups on and get out the door to work and parties. Every chic prep girl was at the W2WW party : Francesca Bodini, Lauren Remington Platt, Chessy Wilson, author Anisha Lakhani, Elizabeth Meigher and TV star Kimberly Guilfoyle. Then there was the grand opening which boasted Sam Ronson as DJ and a star studded red carpet. Think: Ciara, Alessandra Ambrosia, Eric Balfour, Michelle Rodriguez, Danny Masterson, Swizz Beats, Lance Bass (who has become Manhattan's gay man about town, appearing everywhere) and Stephanie Pratt who has morphed from L.A. reality TV star to New York socialite (her BFF is now Marjorie Gubelmann). Since opening, LAVO and the restaurant have been packed, so get uptown and brave that metaphorical nosebleed.
