Classy, traditional, and with a link to the actor who put the sparkle in German wine in 1811, this is the place to share a bottle of Sekt before or after a concert at the Konzerthaus on Gendarmenmarkt. There's a warren of rooms in which to carve out a cosy niche. Germans know their roasts, and you can trust the national committee that dubbed the Sauerbraten here the best in Germany in 2003.
