I'm going to tokyo, so anywhere in that area is OK, a few years back, on a local TV in hong kong, showing tourist all about japan tokyo, and i saw them showing a street where it has mostly all food, from sushi to noodles and, well most junk food like octopus balls, pancakes and skewers, bit like hawkers in korean or bangkok, but mostly just the shops having stalls in front of their shops, the nearest i've found is a street in ueno, but i'm sure thats not the one i'm looking for.
also does anyone know whereabout this restaurant is, link provided, it's somewhere in Jingu-Mae.
and it's nothing illegally, hope my info helps and sorry for all the request.
