Given the retro allure of everything from horn-rimmed glasses to antique barware, it was only a matter of time before someone revived the once ubiquitous soda fountain. Enter Juliet Pries, who opened the Art Deco-accented Ice Cream Bar in San Francisco’s Cole Valley neighborhood in 2012. Since then, legions of ice cream fanatics have walked in and gone “googly-eyed,” as Pries calls it, deliberating between banana pudding and butterscotch, or sweet corn and basil.

He does not get offended if you call him a jerk.
