Been a few times and the food is good - traditional German fayre such as Konigsberger klopse although, perhaps to help recreate that authentic GDR feel, many of the dishes on the menu tend to be "not available"!
Lovely views of the city of course but the things that will drive you crazy is the absurd booking system. Go online (no you can't book there, no you can't book by phone) and fill in an absurdly detailed booking form (your home address etc) where you are asked which days and which time you would like your table. Then click send. Then get an email reply saying this slot is fully booked. Then repeat the whole process again with a new date or time. Then get an email saying this slot is fully booked...then either give up or repeat again and again and again....
