I don't really gamble so i cant recall how we found out about it but every Friday the Deerfoot Inn and Casino has a All-you-can-eat Prime Rib Buffet that is pretty amazing. It also includes a nice salad selection, crab legs, hearty pastas and a large variety of desserts.
I will admit there has been the odd time when the food over all has been just average, especially if it gets really busy which it can but more time then i can remember, Ive left feeling very satisfied and for only $17 bucks, you'll be hard pressed to beat it. Go with a large group of friends and you'll have a blast, i promise.
