Tried this place on a whim last week. Apparently it's been open for 1 year but I hadn't noticed. Then again I've only been in London on and off this last year.
Was surprisingly impressed with the udon soup with tsukune (chicken ball) for £4.70, decent noodles, good [sweet soy] broth, OK chicken balls. Very generous size as well. Sushi (nigiri, rolls and gunkan rolls) weren't bad either. Worth knowing about if you live in the nabe.
