He did mention Tokyo, so Hokkaido will be a bit far. You will have to hunt around Tokyo area, though there are some decent street food around Harajuku area, Also do check out Ueno, there are some nice small restaurant around Ueno station.. Whats your budget? If you want some fine dining type stuff, i do know of one chaya (茶屋）that that also doe Kaiseki, i need to dig up the info for you though
