Bob's Donut & Pastry Shop shared by @infatuation says: ""Bob’s Donuts on Polk Street in Nob Hill fries up incredible classic glazed donuts and apple fritters, all day, every day. Which is great news if you love donuts more than your pet (if so, please consider getting their “giant donut” and taking "The Challenge"). And, cool fact: This 24-hour spot has been churning out puffy, airy classics since the 1960s. Head to Bob’s newer location in NoPa if you’re in the area (though, it’s only open until 9pm)."" on Postcard
