When a doughnut shop doesn’t have a closing time, you might think it’s serving around the clock. We wish. Instead, Gilt Bar’s fried-dough offshoot opens at 8am Tuesdays–Fridays and 9:30am Saturdays, staying open until the last puffy ring is sold, typically before noon. Buttermilk and glazed yeast classics are staples, but the blog and Twitter feed update dough lovers of daily specials that run the gamut from pistachio to birthday cake (that’s a cake doughnut dunked in vanilla glaze and festooned with rainbow sprinkles…duh). 401½ N Franklin St.
