Shinjuku I-land Patio is a place for people to gather for dinner, shopping or simply to sit outside in the open-air courtyard and enjoy the day.
There is a variety of restaurants here, ranging from Italian cuisine to Japanese donkatsu with English menus available. Aside from restaurants, there are also public art exhibitions/installations for everyone to see.
The place gives off a very friendly and lively atmosphere. I would recommend stopping by if you are in the area of Shinjuku.
