Shimokitazawa, or "Shimokita" is one of the coolest places to go, and convenient places to live in Tokyo. It's located a few minutes by train from Shibuya
and has some of the nicest bars, shops, and restaurants hidden away in it's maze of streets. It's also famous for it's theatres, like the Honda Gekijo
. Apparently, people who hang out in Shimokita are called, "Shimokee", although i've never heard it used.
Take the Inokashira line from Shibuya, or the Odakyu line from Shinjuku and you're there.
Don't forget to check out the "Delta Blue" coffee shop, "Artist" bar, and the "Macrophage" t-shirt shop.
