BAR FLAT is a small bar in Yoyogi, Shibuya, Tokyo, a 10- to 15-minute walk from Shinjuku Station. It serves cocktails, craft beer, and whiskey, including a Tokyo Mule and a Moscow Mule made with house-made ginger ale, and a gin gimlet. The owner, Satoshi, speaks fluent English and talks about drinks and Tokyo travel spots, and the walls are lined with whiskey and other bottles. The space holds about 8 to 10 seats, so it is hard to get a seat when full.
