Yoyogi-Koen: Bar
Fuglen (Yoyogi-Koen: Bar)
Open 8am-midnight. Closed Mondays, Tuesdays.
Sun: Open Sundays

Japanese and Norwegian craft beers and artisanal cocktails are served at this very stylish Norwegian bar - the main branch is in Oslo. During the day they offer serious espresso beverages and tea, and attract a good-sized following thanks to the comfortable setting and the free wifi.

If you're very hungry there's also a minimal food menu (e.g. Norwegian salmon sandwiches), but this isn't really a dining destination. Cafe hours are 8am-7pm weekdays and 10am-7pm weekends. The bar is open until midnight Wednesdays and Sundays, 1am Thursdays, and 2am Fridays and Saturdays.

Shibuya-ku, Tomigaya 1-16-11.
