Lots of you tube videos of people going to the casinos with buffets. Most buffets are breakfast, or brunch, with dinner buffets only on certain days of the week. Three factors which make prices higher than before...inflation(roughly 300% from 1980. Less competition(only about 14 buffets in casinos in Vegas) and the range of choices and quality of food is better.
One meal at a decent restaurant sometimes cost more than a good buffet. There are non casinos buffets with decent quality off the strip. There are prime rib dinners at casinos as low as about 12 bucks. But good deals, and good meals can be had at 25-35 bucks...for prime rib.
As COVID fears disappear, I expect competition to heat up and prices will moderate and more casino buffets will reopen.
It was a great deal for about a year and then one day the manager told me they would no longer be taking electronic gift cards. Bummer but a few months later Golden Corral shut down due to Covid. It eventually reopened but only briefly and then most Golden Corrals in the country shut down including all the ones in South Florida.
