I live around the corner and have tried Kirei three times now. I really wanted to like it for convenience sake but won't be going back again.
I have tried their ramen, sushi combo and sashimi tray. The ramen was ok but not very good value as they only give you 2 slices of pork. The nigiri, maki and sashimi weren't good both times that I tried it (most recently last night). The fish was not fresh at all. The salmon was very chewy (I didn't even know that was possible) as were several large chunks in the spicy tuna roll. The albacore tuna was inedible. I actually stopped eating after a couple of pieces for fear of getting sick. The ratio of fish to rice in the nigiri was not right either - too little rice and too much fish but I guess some might like that.
Service was decent and decor is nice but the music they have playing in the background is terrible - think Muzak but worse. We did takeout last night just to avoid the experience.
Perhaps I was unlucky with my experiences but the third time was definitely not the charm in my case!
