What are some of the most unusual themed restaurants, bars or cafes you have been to in Japan?

A couple kissa.

Fukuoka they have a cool “reptile cafe”

There used to be a "no panti kissa" in Shinjuku. Mirror floors and terrible coffee.

There was a "no-pan shabu shabu" restaurant in Kanda years ago and a bar allegedly designed by HR Giger of Alien fame in Shirokanedai in the 1980s.

Kimochi warui (Yuck!).

Probably the cat cafe owned by a cat enthusiast with a cat allergy, so all he can have is mechanical toy cats bumbling around the bar while he is lamenting his predicament in musical performances.

Yoshinoya.

Makes being homeless look luxurious.

Dumbfounded........now that's a good name for a cafe.

Kyoto, the ancient capital and spiritual home of Japan, has a bar called "Hawkwind", no doubt after everyone's favourite space rockers.

I can sing most of the lyrics of the Quark, Strangeness, and Charm album, but have never been to the bar. I'll definitely go next time. I might deliberately go by bus, just make them more crowded and p#$" off some locals.

Sadly NONE.

Sadly NONE.

Don't be sad. Just visit Japan sometime.
