The buzzy stretch of Greenwood Avenue has bars and restaurants and taprooms aplenty, but the 24-hour diner with an adjoined karaoke bar remains a singular treasure. Breakfast and lunch menus are available morning or night; here your last meal of the day may actually be the most important one after drunkenly singing bygone hits in the bar opposite the diner’s entrance. Plop down in a glittery vinyl booth beside a wall of mounted astronaut portraits or in a seat near draped faux ivy to peruse a menu just as eclectic as the surroundings: buttermilk pancakes, chilaquiles with housemade chorizo, meatloaf, a crabby bacon melt on grilled sourdough. Then there’s the simple blessing of a baked potato which comes with its own toppings card because, per the menu, North Star will “put anything on this baked potato!”
