Coupon book specifies lunch only. After standing in line for 30 mins on Saturday...counter lady says... Coupon isn't good today, because Saturday's we serve Brunch...NOT lunch. I guess I'm supposed to know that, but since most of the coupons are specific, if they are only good on certain days... I didn't. So, we walked across the street to Mirage and used the 2-4-1 for their BRUNCH, and were very pleased. Awesome priime rib..crab legs, free champagne. Thanks Harrah's for sending me across the street for a much better buffet!!
