I was VERY curious about Jean Phillippe because I visited their location in the Bellagio years ago and admired their chocolate fountain and beautiful pastries, unsure if they were famous for their presentation than for the taste. Well, Yelp reviews gave JP a solid 4-star review at both their locations (they are now in the Aria) and I had to give it a shot. They are open 24 hours but I made sure to pick up pastries bright and early while they were fresh, the pastries come out at 7am.
* JP is famous for their nutella brioche and croissants
* The croissant is flaky but nothing special, the best part is the chocolate which is rich and bittersweet but I wish there was more.
* The brioche bread is too dense and tastes like a dinner roll with a huge gob of nutella. Very mediocre.
* Ham and Cheese croissant was overly decadent and soggy because of the bechamel inside.
Jean Phillippe has some beautiful desserts I may give them a second chance but do not recommend the pastries.
