Only in Japan...
I recently went to a traditional Japanese festival in Ikebukuro, Tokyo which was naturally outdoors, displaying lots of Japanese cultural and religious history and background. I've been to a Japanese festival before and wasn't surprised to see the big parade, nor the tonnes of delicious Japanese food, nor the traditional Japanese dancing and drumming.
However, I really didn't expect to see a full bar with servers dressed up in tuxedos, especially since the event was outdoors and so casual. But of course anything is possible in this country!!!
