Yajiumatei is a teppanyaki restaurant in Nishiikebukuro, Toshima City, Tokyo, serving monjayaki, okonomiyaki and yakisoba to a mostly local crowd. Guests cook the monjayaki and yakisoba themselves on the griddle, and staff show first-timers how to do it or cook it for them. The restaurant occupies the basement and second floors, and the second floor has floor seating. Smoking is allowed indoors, which is uncomfortable for anyone sensitive to cigarette smoke.
