A casual restaurant and bar called Dudley’s opened last night in the former home of Little Giant, at Orchard and Broome. When we stopped by today, we got a peek at the menu, which we’re told is still evolving — it’s a straightforward lineup of burgers, pasta, crostini, and simple apps including a kale Caesar. There’s a full liquor license, with cocktails served from behind the curving marble bar. The exterior has been redone in a slate blue, and windows still swing wide open to create an open-air feel (sidewalk seating is in the works). For now the spot is dinner only, pouring drinks till 2 a.m. Head on down and say hello.
