Britannia Sushi is great for a discount sushi joint. The tuna, yam, and salmon rolls have nice thick thumb sized pieces of fish (or yam) in them and the quality is consistently high. It's obviously a family run place and one gets the impression that the staff would rather be doing something else. The soft rock on the radio is a bit annoying but you probably shoudn't be coming here expecting an authentic Japanese experience. Some previous reviewers mentioned poor hygiene and that may well be the case but I haven't seen anything remarkably concerning, however, there have been a couple of occasions of stomach distress a couple of hours after eating there.
