Cafe Harvest combines a vintage Austrian atmosphere with a fully vegan menu featuring traditional dishes like soy schnitzel, vegan kebap, and soy goulash served alongside a wide selection of vegan cakes. Cash only and wheelchair accessible, it is especially known for its weekend vegan brunch buffet and cozy indoor and outdoor seating with views of Karmeliterplatz. Guests appreciate the friendly service, quick seating without required reservations on weekdays, and the inclusion of gluten-free options, though some note the vegan Kaiserschmarrn can be hit or miss.
