Shinjuku has its fair share of beer gardens, but Keio's rooftop spot edges most of the competition with its impressive night views, number of seats and affordable set menus. Their affordable happy-hour plate (¥2,970) is available only to those who arrive before 5.30pm, and includes 90 minutes of free-flow drinks along with roast pork, cucumber, and tortilla chips.
The more complete eight-course menu, complete with two hours of free-flowing drinks (¥4,400/person) is recommended for groups of two or more, while the slightly more extravagant nine-course menu (¥5,830) with grilled chicken and cocktail shrimp is perfect for special occasions.
Reservations are essential and can be made online.
