Conference Dinner
The conference dinner will take place at Habel Weinkultur in Mitte, not far from the "Brandenburger Tor" (plan). I reserve the table at 20:00 (25. September 2007).
I order the "Berlin Menu No. 1":
- Berlin ceps-potato-soup with fresh marjoram
- Smoked saddle of young pork with cumin gravy on Riesling sauerkraut with herbs potatoes
- Marinated berries with honey- poppy seed- vanilla sauce
If somebody don't like pork, please inform me 10 days before! I will order the meals at the 17th September.
So you can eat the "Berlin Menu No. 2"
- Berlin cray-fish soup with crayfish tails
- Pike perch fillets roasted on the skin on black salsify with leek and peas and to herbs- rice edge
- Apple fritters in hot pepper-cinnamon-sugar on wild berry cream
or a "Vegetarian" Menu.
Feel free to add this information in the list of attendees.
There is time for a "small" sight seeing tour before or/and after the dinner.
