Mirazur in Menton, France, is the No. 1 restaurant in the world. This is the first time chef Mauro Colagreco and his sunny Provencal dining room have clinched the top spot; previously the restaurant was No. 3. This is also the first time France has gotten the No. 1 spot since the awards began 18 years ago. That’s in part because executives behind the World’s 50 Best Restaurants list made a profound change to the rules this year, decreeing that no previous winner can be No.
