Hawaian inspired tiny tiki bar, just a round corner form Shimokitazawa Station. Super nice decoration / owners personal skateboard collection, wired plants etc. Best Mojito in Tokyo! 

Calm and quiet place to drink tea and enjoy a nice conversation.

If you are into "Midnight Diner"-esque night experience but not into a crowded Shinjuku scale, then this is a good alternative. Smaller and much more laid back.

The Tsukiji Market ( Chuo-ku ) If you want to eat Sushi, you should go to Tsukiji not Ginza. This is the biggest market in the world. You can get better quality fish than anywhere else. The auction and cleaning of big fish are worth seeing. I aways come by the first train, take some photo, eat rice bowl dishes.

Omiya Pastry Shop is an open self-service shop, with an atmosphere of unique and elegant calm, reasonable prices, and a basic flavor. The space and the taste is satisfactory on every count. The interior gives me the feeling that I've gone back in time to Japan's Showa period.
