i was there at friday dinner buffet, i think this buffet doesn't reflect a 5 star hotel, it's poor! plus the seafood, and sushi station wasn't tasty at all, i couldn't eat even one piece of sushi although it's my favorite food. i couldn't try all of it of course but i can say that the grilled chicken was amazing, since the chef prepare it on spot, and the pasta was nice. the good thing is that they use a very good quality of meat (beef and lamb) and you can notice that.
the service was very good. they refill constantly to maintain the presentation as possible.
