There is nothing "wrong" with Sushi Bay, rather there is nothing brilliant about it either!
I would say based on quality and quantity dishes are on the expensive side and really too many which are just too average rather than being special. Dishes like the Karaage Chicken were good, but no level of flavours which are found at other restaurants.
If you want Sushi or Japanese , this place is "fine" but again a little pricey. Nothing wrong overall.
