Sounds like a great place. It'll go on my list for when I'm in Tokyo in September.

While doing a little searching on line to find co co locations I came across this on their website: "March 2010: Opened "Nikkui Tei" Konan Akadoji restaurant, a new type of restaurant specializing in Hamburger steak."

The photos on the Japanese-only associated site look good enough to eat. Has anyone been to this new chain and know where they are located?
