The aroma of coffee has been scientifically proven to create happiness, so it should come as no surprise that the line of people waiting outside tiny Café Wacker first thing in the morning is a kaleidoscope neighborhood residents. This coffee roaster has been an institution since 1914. With its carved cabinets, a collection of coffee makers from countries around the world, and a spacious terrace, Café Wacker is a destination you shouldn’t miss.
