I'm not really sure how you can make sushi taste boring or awful, but Aji Sai has done it.
Quite an achievement, I think.
All you can eat sushi should not mean terrible quality, but that's precisely how it is at Aji Sai. My friend warned me, even, walking in, that it would be sub-par, but I don't think I was quite prepared for how genuinely bad the sushi is.
I'm pleasantly surprised I didn't get sick, and that's not a thought you want to be having after eating at a sushi restaurant.
