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.
This book will introduce you to more than twenty of Japan's favorite specialty foods that are less well known abroad, along with a guide to the best places in Tokyo to try them and expert tips on what to order. From Bento.com.
