Pub and Kitchen in Philadelphia just retired their Windsor Burger to make way for the sautéed onion-topped Churchill Burger ($18) made with an eight-ounce custom beef blend patty from Pat LaFrieda, a first for the city. (Other restaurants in Philly—The Continental, Coco's, and Jones, to name a few—serve Pat LaFrieda burgers that aren't custom blended.) Other places that serve custom-blended Pat LaFrieda patties include Minetta Tavern and The Spotted Pig in New York City. Read more about the burger at Philadelphia City Paper's food blog, Meal Ticket.
