A café as lovely and sunny as this inspires lingering. But lingering requires cup upon cup of caffeine, and that could become hazardous. This European export has a solution for that, though: a full menu of food, most of it the unlikeliest coffeehouse food you’ve come across. Frittaten soup is offered daily, and the roasted lamb is served with golden, toothsome spaetzle. At the end of the meal, a slice of impeccable opera cake is a necessity. And with it, yet another cup of coffee.
