We've eaten at the GC buffet 3 times and consider it the worst of the 4 main Boyd properties. I play DDB and almost all of Orleans DDB machines are FP...very few of GC are. Only positive we have for the GC is its ice cream parlor...its great.
Orleans also has a showroom with a constant rotation of "once-big" names performing. Fairly easy comp if you are playing at either the Orleans or the Gold Coast if they are not sold out but of course its much more convenient from the Orleans.
