We visited this cafe during a trip to Kusatsu-Onsen in Japan. We did not expect much but it turned out that the food, service, interior is very nice. Most of the customers seemed like tourist who just need a quick rest, which I think is a waste for a nice cafe like this. As for us, we spent more than an hour here, having the best esperience in this little town famous for its hot spring, not its coffee:)
P.S. The name "Gute Reise" was taken from German which means "Bon Voyage".
