Sushi in Dublin

What is the deal with Sushi in Dublin?? Places I know where to get it are, Tesco (Aya), Marks & Spencers, Aya and Yamamori.

I'd love to know any other places to get some.

Its says alot about Irish tastes that the choice is so very limited. Its shocking that there is only one sushi restaurant in a city this size.

Aya is about as good as it gets in my experience - the range of choice and standard isn't great here unfortunately.
