Jinnan cafe in shibuya is a relaxing place to have a drink. In Tokyo there are only few places where you can go an order drink only. This place is also very spacious and quiet for shibuya . It's not in anyway exceedingly good, just a relaxing bar/cafe/restaurant that you can go in shibuya.
Toritake -- 鳥竹 Toritake is an awesome Yakitori place located right by Shibuya station. It’s a hole-in-the-wall Izakaya kind of place and has three floors which are constantly packed with customers. Be prepared to wait a little during popular hours.
