The Sauerbraten and the Jagerschnitzel are quite good. The Spaten Optimator double bock on tap is great, and they have Rauchbier in bottles.
You get what you pay for--good espresso, luscious lemon tarts, Dammann Freres tea, madeleines, more. Authentic + delicious. I <3 the apple danish, too. Achtung: NO soy drinks here if you're lac-intol.
Hip space, the very best Indian food in DC. The Palak Chaat is a must, but really can't go wrong with any dish. Plan ahead, reservations are difficult to get. Or show up with your fingers crossed.
