Royal Palace Restaurant is located in the Stadium Shopping Center right next to the Ice Palace.
I have to say the Royal Palace Restaurant has one of the best Chinese buffet on the island.
They have a good selection of food and all of it is very tasty. The cake noodles is very delicious, though they have the tendency to get really hard, so you gotta look for the ones that are a bit soft in the middle. Also their ginger chicken is really good and their sauce is perfect. They also have chicken with green beans and beef broccoli which is very good. And for dessert, you should try their taro tapioca it is awesome.
And for the price, $9.50 you can't really beat it.
