Wasabi

Has the look and feel of a sandwich shop like Pret, but instead of sandwiches, its Sushi thats on the shelves
Prices are good - each piece of sushi is individually wrapped (or in pairs if rolls) and the price is generally about £ 1 for 2
Selection is good with Snapper and Octopus being noted among the Salmon and Tuna, there was more but I cant really remember.
They also do hot food - the usual suspects were there, Teriyaki etc which are served with rice and are about £ 3.50
I went for a pre-prepared sushi selection for £ 6 - although this went up to £ 6.20 by the time I added a sachet of Soy, Wasabi and 2 of Gari - 5p each is not too bad, would get 2 Soy next time though.
Chop Sticks are provided, as are little plastic pots to put your Soy/Wasabi/Gari into - I recall 2 pots
The pre-prepared selections are not put together to a recipe, ie the contents vary in composition - so browse and choose the one that has what you like in it, or browse to avoid what you dont want.
