The Feast Buffet at Green Valley and Red Rock are the best. They offer a huge selection of different food items. Don't pass up dessert though and try the spumoni ice cream. You can also have milkshakes made to order. You should definitely get the Station Casino Boarding Pass (even if you don't gamble) so that you can get discounts at the buffet. If you do gamble and spend boat-loads of money, you can get upgraded to Platinum and Chairman status and don't have to wait in line for the buffet.
