Furnished with Eames plastic side chairs and bright-blue subway tiles, Carl Ludwig Cafe is one of the outlets for good coffee near Karlsplatz in District 4. The highlight is the outdoor terrace, overlooking the green interior courtyard of the palace that once belonged to Archduke Carl Ludwig, a younger brother of Emperor Franz Joseph and the dedicatee of the current premises. Students from the nearby University of Technology make up most customers. Lingering is welcome, wifi available.
