This branch of Hyaku Ban (there are several) is near Fudomae station in Nishi Gotanda. The lunch teishoku was decent but unremarkable, a ramen + rice + scrambled egg set. The ramen was Tokyo shoyu style and tasted very "regular". There weren't many people in the store at the time I went. If you are in need of a cheap meal, this is acceptable, but Chinese Cafe 8 would be a better choice for cheap Chinese food. I have to admit that they did have a large number of things on the menu (but few pictures though) and if you want to have a large number of things to choose from it might be worth a try.
