Kagurazaka Beer Garden
Time Out says
As if having the plummiest terrace in the area wasn't enough, Kagurazaka Stagione has opened a beer garden up on the roof. Beer and spumanti goes for ¥650 a glass, and the menu includes ¥600 antipasti plates and the restaurant's trademark Napolitan pizzas. There's only space for 20 people, so reservations are pretty much essential.
