Wanting to have some good mussels in Geneva, I decided to try Francis after reading the Tripadvisor reviews. I took the mussels as a starter. Normally the chef has A.O.P. mussels from the Mont Saint Michel area but it's not yet the season. Even so, they were from Normandy and, I have to say, quite succulent.
As a main, I had the breaded veal "elephant ear" style and my brother had the sea bass. Both were perfectly cooked and well presented.
The decoration is quite old-fashioned and rustic which gives the place an authentic feeling of being transported to Brittany, the owner's homeland. He was very generous and welcoming and did not hesitate to chat with the guests without being too invasive or forgetful of his tasks at hand.
They offer mussels as a starter but mainly as a main course, with at least 8 different sauces to choose from. This is the true reason you should come here.
A ten minute walk from the train station and not far from the banking quarter, Manor, or the Mandarin Oriental Hotel, the Francis is perfectly located. Depending on the time of day, parking can be tough, so if you can't come by public transport (the tram stops practically in front of the restaurant), there is the nearby parking du Seujet, or try your luck with white or blue parking spots.
I highly recommend Francis as an authentic, no-nonsense place where I have now found the best mussels in town!
