I went to this place a few days after I came back from Japan. That might be one of the reasons why I thought it was really bad, as opposed to bad.
First of all, they slice the fish really small and thin, and they put way too much rice in each peace of nigiri. The taste of the fish is meh at best. Also, I don't know if they messed up the preparation of the rice, but it just wasn't right (the taste of sugar was overpowering). The rolls I got were messy and had too much rice as well.
I got tempura shrimp too but they were soggy and cold. At least the miso soup was good.
You know that feeling you get, when you put a perfect piece of sushi in your mouth? You eyes open up widely, the fish melts in your mouth, a party of flavours starts to form in mouth... it's controlled yet it's a blast... well, you will never have that feeling here.
I won't go back.
