We went twice in 2003 (we were staying at the WL) and loved it. Once on that trip, our server wasn't too into it, maybe because we were so tired after the long trip, but others around us were having lots of fun, and the whole place was a blast. On our second visit that trip, our server was way into it, and we thoroughly enjoyed it.
Because we had such a blast in 2003, we made a special trip over there from the Polynesian in July, and were so very disappointed. Our server wasn't part of it at all, and the entire place was quieter than before. I could see an overall tamer atmosphere there--and it's not just because of our server. I also think the food quality declined too.
If I were staying at the WL, I'd eat there, but otherwise, I do not think it is worthy of a special trip to the WL. Of course, if you hadn't been there before, you wouldn't be comparing it to the past, as we were. My kids and DH also don't have a desire to go back, either, so when we go back to WDW next year, we'll try something new.
