I'm surprised by the relatively poor reviews Sushi D has received.
I'm not usually a fan of AYCE but here that's the best option so that you can experience the variety of Sushi D. Okay - some of their creations are not great (e.g. treasure island). but the Rock Shrimp are outstanding, as is the spicy tuna. The restaurant is attractive and service is friendly. This is my goto Sushi Restaurant.
