For more than 100 years, Crown Candy Kitchen has held down the corner of North 14th Street and St. Louis Avenue. Though the city has evolved around it, not much has changed at the historic soda fountain and diner. Structurally, the restaurant is nearly the same as it was when it opened, the only major changes being some paint and detailing to keep it looking fresh. “We don’t change things around here. Change, I tell people, is a bad thing around here,” said co-owner Andy Karandzieff, whose grandfather, Harry Karandzieff, started the restaurant in 1913.
