Came here with a relatively large group of friends (about ten) and were given a separate room upstairs.
Started with a nice amuse bouche and their recommended aperitif (10+ EUR - I think this is where they make a lot of their money). Then we had a nice mix of the two different set meals that were both outstanding (foie gras, lobster, frog, lamb etc) and not too aggressively priced (60-80 EUR). Also had some very nice local wine. Overall excellent quality for around 100 EUR pp.
Service started out quite disappointing (it took us a good 45-60 minutes to order wine, we had to ask for water about 5 times and the food arrived veeeery slowly). Things did get better once the more experience waiter freed up a little from serving downstairs and in the end they offered us coffee and a digestif on the house.
Can definitely recommend the place but would try to be seated downstairs to avoid the slow service.
