We rarely miss it. Its all what the above posters state and then some. Hasn't change since we've been going in 1977. All the beer and sangria you want, fried chicken, second to none, corn, ribs, salad and strawberry short pie. You just start laughing as soon as the show starts which is about 5 minutes after you're seated and you have to join in.
Its at FW, tough place to get to if you're not too familar with WDW but doeable. We really prefer the ground floor over the balconies, have no idea how they seat, I think others may know that answer and reservations are hard to get, some book out year in advance, depends on time of year and seating, there's 3 seating a night.
Go, you'll enjoy it and have sore ribs like the rest of us HDDR lovers. Its the longest standing show on property.
