Not sure what happened. I went when it was beside the theatre first of all and thought it was amazing, then when I went to it at Justice Mill Lane I thought I had died and gone to heaven. More expansive menu, good vibe about the place and I used to eat my body weight in sushi. Then it went back to beside the theatre and they changed the menu to Scottish-Asian fusion, which meant no more sushi
I didn't go back and it closed down a few months later.
On a side note, I used to have this Japanese lemonade that was in a weird bottle with a glass ball floating in it. It was really fine but hadn't seen it since my last visit to Yatai. When in Copenhagen in the summer, I visited a sushi bar and they had it on the menu. So I got really excited about tasting this lemonade again only to be told that no where in the world has it now as the factory got washed away in the tsunami
