Here's the thing about the food at HDDR: It is fried chicken and ribs, with some side dishes, and a strawberry shortcake dessert. That's what it is! Don't go expecting a gourmet meal, since food alone is really not what you're paying for. It is a dinner show...all-you-can-eat food...AND (very fun, IMO) entertainment. (Incidentally, also all-you-can-drink beer, wine and sangria, which are not included in most of the prix-fixed meals. The sangria is yummy!) The chicken and ribs are delicious, IMO. If you find yours are too dry, tell your server and ask for a different bucket. You can ask for more or less bbq sauce, etc. You can probably ask for a hamburger or a plate of spaghetti if you don't like these. There are some other options for the kids, like PB&J or mac & cheese, but you have to ask. This experience is not about the food. I happen to love fried chicken and ribs, and actually only eat them ever at HDDR, so it's a treat for me.
The entertainment is very corny. If your family rolls their eyes up into their heads over cornball humor, this is not the show for you. If you can sit back and enjoy silly antics, give it a try! We think it is leg-slappin' hilarious!
HDDR is our FAVORITE WDW experience over four generations. My kids insist on going back next time. DH wouldn't consider going to WDW without HDDR. I have converted them. Others hate it and say it's not worth it! We think it is a small price to pay for the experience and consider HDDR one of the best values in WDW! It depends upon your personal taste. I think if it fits into your budget, it might be worth trying once!
Never done WC, so sorry, I can't compare the two. Whatever you do, give us a review when you return!
(Sorry so long...this is one of my passions.)
