We've done the WDW luau at the Poly and the Hoop De Do Review, both were a lot of fun. We enjoyed the luau so much we went back for a 2nd year in a row this year, couldn't get tickets to HDDR so that pretty much determined what we were going to see. Both of those shows seem much more "kid" oriented, much like the other area dinner shows. Cirque du Soleil is much more "adult" oriented, if you like that sort of thing I would always recommend Cirque over the others. The food at most dinner/show combos isn't the best anyhow...at Cirque, you can eat a "real" dinner in one of the excellent DTD restaurants there.. and then go see a top notch show...really the best of both worlds..but Cirque tickets aren't cheap!
Raglan Road or Adventurer's Club at PI could almost be considered dinner shows...certainly lively entertainment! (Although AC has no food). House of Blues also has excellent food, and shows, depending on your musical tastes and who's playing that evening, we were just there last month and at all of these places and had an excellent time! (Although for dinner we "ate around the world" at Epcot that evening before hitting HOB and PI).
