As a longtime Williamsburg favorite since 1973,  Kellogg’s diner has become the go-to greasy spoon thanks to its 24-hour menu. Located on 518 Metropolitan Ave. in Brooklyn, the stand-alone diner received a makeover in 2008, following its 35th anniversary. For locals who were used to its familiar facade, the change was almost “too new.” It now boasts a shiny chrome exterior, a full bar and a new sign.
