Heidelberg's oldest (1863) coffeehouse has always been a popular meeting place for students and professors, and offers traditional Schwabian food, pastries and ambiance. A historic change is that café no longer is producing café founder Fridolin Knösel's Heidelberger Studentenkuss. This iconic "student kiss" is a chocolate wrapped in paper showing two sets of touching lips—an acceptable way for 19th-century students to "exchange kisses" in public. They are
now being sold exclusively in Knösel Chocolatier, a small, charming shop, owned by the Knösel family, just down the street.
