Last night at Peter Luger, around 9 p.m., Lindsay Lohan dined with a large party, sporting black patent-leather quilted ankle boots with black semi-opaque tights and a black crushed velvet jacket that came to mid-thigh. One man who wasn’t fazed by this? Waiter Bernard Patten. Since moving from his native Dublin in 1985, he’s seen it all, first at the Waldorf-Astoria and then, for the past eighteen years, at Luger. The Williamsburg bastion of dependability has been going through some changes lately — a new steak on the menu, an expanded kitchen, and a new dining room (seen here) that Patten tells us has eased waiting times. In about six months, there will also be an upstairs lounge and bar with an adjoining private-party space. We asked Patten how he’s been weathering the changes.
