Hmmm I honestly don't know if I have any good tips for finding the best DL deals. It's been a few years...I'm feeling rusty!
But I absolutely have to recommend Goofy's Kitchen for character dining. It is the BEST, we love it!!
(Think the West Coast version of Chef Mickey's...only better. Haha.) We actually had our wedding dinner there, lol. I'm also a fan of Plaza Inn - though I've never actually "eaten" there technically, I've been there many times as...er, entertainment!
I think it's a great atmosphere.
