My husband and I were feeling like trying a new sushi restaurant tonight (a Thursday) as we typically frequent Ra (love their sushi and HH) or Hon Machi (really good sushi too). I searched for best sushi Phoenix, and Sekai came up as best for Citysearch. After seeing all the great reviews, we drove out from Chandler.
When we got our food, it was not good at all. The fish was warm, I think it was because the sushi rice was hot when the put the fish on it. It also didn't taste nigiri very fresh.
As for the rolls, the eel sauce was way too sweet and very runny. The avocado was brown and mushy, and there was way too much rice (again, not very good sushi rice) on each roll. I couldn't eat more than a few pieces, it was awful.
To top it off, the waitstaff wasn't great. We both finished our waters, and it wasn't until the bill was brought to us (after sitting for awhile not touching the bad food) that someone realized we were out of water.
In sum, I have NO idea how this place got to be rated so high. Yes, they are big, as they are full of bad rice, but they taste awful. My guess - the waitstaff voted on their own restaurant.
