I've been to Tokyo a few times but will be heading to Tokyo with a friend who's never been - unfortunately we're just there on a brief layover. I expect we'll arrive in town by 9PM on a Sunday.
I imagine ramen and yakitori will be perhaps the easiest to find. Or perhaps izakayas?
Any recommendations for a few places to check out that are concentrated in the same area? (eg: Shinjuku or Shibuya?)
