We ate there this past week (Thursday night) and it was the only disappointing meal of our nine day trip. There were plenty of shenanigans, but they seemed forced and the servers seemed to be going through the motions. Our server was a bit odd, and I think that may have been her attempt at being "in character" but it came off as aloof, instead. We love character and theme meals, but this one just didn't land for us.
The food was also really a disappointment. I am a bit of a BBQ snob, and in all honesty the brisket was quite good (leading me to suspect they used a pre-smoked, reheated product, as brisket is usually the hardest to execute successfully) and the ribs were slightly better than average (I like St. Louis ribs, but those who seek baby backs may be disappointed), but the pulled pork was exceedingly fatty, the chicken was flabby and the slaw was mushy. The cornbread was tasty, and our server let me share with our table, which was a very nice touch. I found the BBQ sauce to be too sweet, but that is totally a personal preference and not an issue with their sauce but rather my palate.
My wife got the smoked pork loin with the Tillamook & chorizo grits. The grits were very good but refrigerator cold (not sure if that was intended or an error by the kitchen, but our server disappeared for a while so she ate them and found them good, just oddly cold) and the pork loin was more heft than flavor. Our daughter ordered the kid rib meal and declared them OK, but not great (she's a BBQ snob, as well). Our son sucked down several portions of baked beans, so I assume those were good.
Desserts were cold and tasteless, both the apple pie and pecan pie. Both were huge portions, but again almost devoid of taste.
That having been said, tons of people love WCC, so our experience may well have been just an "off night" for the kitchen and crew, or a mismatching of our palates to their menu, but we won't be rushing back. You should certainly give it a try for yourself if you like the look of it, however, and don't take our word for it!
