I can sum this up pretty quickly.
Long wait if you dine late at night. Apparently it's because they don't have anyone to clear tables because when I finally got to pay my $22 (comped, fortunately) I was lead past more than a few dirty tables that I could have been seated at if they had been cleaned.
I liked the barbecue varieties, but the Cajun food I tried was kinda gross. So were the "Chef's Specialty" barbecue chicken wings (very dry and obviously sitting under heat lamps for a long time). Dessert kinda saved the day, but it wasn't enough for me to cheer about.
Go if you must, but if you're looking for a "destination buffet" this isn't it.
