As a few other reviewers have attested, this place is 100% fishy as hell! Their basic spiel is to discriminate customers based on their appearance.
We were 3 of us (myself a long-time Japan resident and my brothers traveling from overseas) looking for this restaurant in Sankita street when this big guy in an apron came and told us they were full (they didn't look like they were full at all) but that we could go for Teppanyaki at a nearby restaurant which they would guide us to. He kept pushing us to go for Teppanyaki for an "authentic Japanese experience".
There seemed to be something fishy here right from the get-go because the staff inside the main restaurant couldn't decide if they were actually full or not. Finally they decided they indeed were full and handed us over to the guy in the apron.
After some deliberation we decided we'd like to try Teppanyaki as the prices seemed reasonable at the main store - ranging from 3000 to 15000 yen. We were guided to the store across the street (in picture). Don't make the mistake we did by agreeing to come here!
The chef in this new restaurant waited for us outside, and mouthed a loud expletive as soon as he set eyes on us. We thought we must have misheard him, so we walked in and were rudely asked to close the door and be seated immediately. Clearly he didn't like having to serve the likes of us. He pushed an English menu in front of us with extremely high prices (most dishes costing over 20000 yen, and some going all the way up to 90000 yen). We asked for the basic course which seemed reasonable, but he said they were out of stock.
We decided to leave because we weren't made to feel comfortable. None of us have been treated this badly at a restaurant in our entire lives.
We can't comment on the food here - maybe it has the character that the chef sorely lacks - but we certainly wouldn't be surprised if there's some fishiness at play here as well.
