When we went (4/11) there was no breakfast buffet - they really need to update this coupon. Website says breakfast buffet only on Friday and Saturday. We do like their buffet compared to similar ones - it is better than Terribles, Palace Station, and far better than AZ Charlies Boulder, and Sam's.
We did not stay at AZ Charlies but did go there for breakfast several times. Steak and eggs or large ham steak and eggs are on special every day with your card and are very good. Steak is not large but tasty. Ham is very large and good. And the price is right. Service is excellent.
