Café Palais Royal
Rule of thumb: the closer you are to monuments, the worse the service gets. As Yelp user Alina M. puts it, “The staff is extremely rude and they don't care about the quality of services. Once Paris was the capital of good manners and good taste. Now it is the capital of rude and really cheap people. Shame to Cafe Royal! There is nothing royal about you.” Man, we can only imagine what the waiter said/did. To top it all off, you just might get hit on by a waiter according to TripAdvisor user kar00, “For a French restaurant you are always guaranteed a bread basket but not here. The staff in general weren't great and some rather pervy.”
Official Snootiness Rating: Pervy doesn't necessarily mean snooty, so a solid 5.
L’Ami Louis is a bit of an institution, but as Vanity Fair writer A. A. Gill tells us "The staff are paunchy, combative, surly men, bulging out of their white jackets with the meaty malevolence of gouty buffalo. They exude a pantomime insolence... As you walk in, one approaches with an eyebrow raised and nose aloft to give you the benefit of full-frontal froggy nostril." Also, equally eloquently, TripAdvisor user J Rosenfield points out. “I had to go more than once to really find that the most ignorant rude slug in the world really works there and calls himself Louis. I practically lost my appetite when he grunted us upon arrival.”
