Of the plethora of choices for Harrah's properties, PH has the best buffet of all of them. I rate Paris next in line. One way to know is how they make some of their food. For instance, the creamed chipped beef and corned beef hash are all made fresh. While at Harrahs, and the others, it is from a can. The Flamingo has gone up in standards a bit, but Harrah's and Paris have gone down hill some. If you are going to do the 24 hour buffet I would do PH as your main choice to eat.
For dinner, they have the best choices of all the other buffets and really do the crab legs well with both warm and cold legs. They also have peel and eat shrimp already peeled for you. That little step saves a ton of mess and time. It is worth the crab legs just to eat there.
Service is friendly and the staff were attentive to us. If you are Diamond or Platinum they make sure you are taken care of right away.
Make no mistake PH doesn't get five stars because it is not on the caliber of MGM or Bellagio. But for Harrah's properties, it is the best.
