Shiori is one of the most exclusive dining experiences in Berlin, with only 10 seats for dinner every night. A eight-course omakase meal that renews every month is what's on the menu, and you won't know what you're indulging in until you get there promptly at 7:30pm. The secrecy is worth the price at this underground Japanese restaurant that includes special touches such as handmade wooden bowls and volcanic stone cups.
