The best restaurants serving Japanese food in Southern NI

Unfortunately the place is a little run down, tired and looks a bit grim. No fish or veggie options and very limited for lunch. Available food is decent enough just a shame it's beef/chicken curry or sweet and sour beef/chicken. Venue is cash only which is irritating because the only cash machine close by charges you to use it. A can of Coke Zero is charged at £2.80. Lastly be careful in the bathroom as the floor is a literal ice rink.
