Jean-Francois Rouquette at the Park Hyatt, Paris
This is a very good place. I enjoyed very much the tasting menu there.
But as in any Hyatt IMO, you feel you could be almost anywhere in the world. When you travel a lot that's a comfortable feeling. Some people however prefer to grab a little bit of the soul of Paris instead.
At the same time, to have fine dining on a Sunday night in the neighborhood is not an easy task.
