If I take people from other countries to somewhere in Japan, I would take them to Izakaya. I think it is really good way to show one of Japanese cultures. Japanese love Izakaya, they go to Izakaya especially on weekend. We can chatting alot with drinking and eating there, and by doing so getting know eath other would be easier if you take someone you don’t know very much . Most of Izakaya have “All you can eat and drink plan” in their menu. As far as I know almost everyone (even people from other countries) loves that kind of stuff. Lately, thare are many kinds of different Izakaya in Japan. One of them which I really want to go is “Ninjya-Yashiki” which is in Shinjyuku. the concept is Ninjya residence, so it might be a good place to go with your friends.
