Squeezed between two medical schools, this old-fashioned pastry shop gets its share of students and professors in need of a nosh. And this is a nosher’s heaven: It has a huge selection of pastries, including Viennese classics like Linzer torte and strudel, and the hot chocolate is one of the best in the city (4€–5€). It’s thick and dark and bitter—sugar cubes are provided so you can adjust the sweetness—and if you ask for it à la viennoise, it will come with a dollop of real whipped cream. The tiny dining area looks like it hasn’t changed in at least 50 years: a collection of wooden booths and small tables that might have been shipped in from Vienna. You can also lunch here on a variety of inexpensive quiches, salads, and pasta dishes, including some nice vegetarian choices.
