Café Neko, Vienna

For those who love cats and coffee, Café Neko in Vienna is the ultimate destination. The café, named after the Japanese word for cat, "neko," serves a standard café menu of drinks and small bites while several cats roam freely around the room. The purpose of the café is so that people who can’t own pets can come in and interact with the cats while they enjoy a cup of coffee.
