Brunch was not very good however I am comparing it with some of the best brunches in the valley, T Cooks at the Royal Palms is about the same price and amazing. However I expected more from Ko Sin because I've eaten at the restaurant just above, Kai, which was outstanding. Ko Sin is decent brunch buffet for the price but a let down with high expectations I had. Do not expect anything like their restaurant upstairs. $20 per adult, $10 per child. Make the drive to Royal Palms in Phoenix....
