I think it is 15 dollars for all you can eat prime rib. It is not listed on their menu, but they did put huge banners advertising it all over Circus Circus. Their prime rib is well made and uses good cuts of meat. It is juicy, tender, and full of flavor. Prime rib comes with au jus dip with tastes great. Customer service is fast, efficient, and friendly. They are open to 11 am and located on the promenade level in Circus Circus hotel and casino. They offer good value. I was pretty happy with my visit. The chocolate fudge vanilla ice cream desert is pretty good.
