My husband and I ate at Monsieur Paul on Dec 30 and we had a lovely time. They did accommodate my dietary intolerance and I am confident that they would accommodate allergies as well.
The service was delightful, the vast majority (if not all) cast members at MP were French citizens and when our waiter discovered I liked using French he happily communicated with me in French and repeated everything again in English for my husband. It was by far our best meal at the Disney Parks and the wine pairings were perfect (we discovered the pear’s extremely alcoholic answer to calvados). We had a few standout dishes (sea bass in puff pastry), a solid cheese plate, and the best apple tart of our lives (the chocolate sphere was good too).
If you are used to paying NY or Paris prices for fine dining it will seem like a good value, but it is still in a theme park and not quite as fancy (or sophisticated) as the best restaurants in the world.
