having read the promising reviews on this site, my colleague and I went to Oishii. The somewhat shoddy interior (e.g. still tape on the walls after a painting job was done) should have warned us that is more the cheap student sushi bar, rather than a Japanese restaurant. We ordered a mixed plate of sushi and sashimi. The tuna was grey and tasteless, we ignored the surimi crab-imitation on the plate, and when looking at the maki rolls, thought the chef was more of an eager amateur than a Japanese master. For 2p we paid 35eur, for which you obviously cannot expect the world. So, if you're looking for a quick and cheap sushi bite, this is spot to hit. if you really want to enjoy good Japanese food, better to go somewhere else.
