I've eaten there twice. The food was fine (I'm not a picky eater), and the interaction was great. The first time I took my Goddaughter for her 9th Birthday (which was also MY birthday) - she'd had the whole BBB that day, and Prince Charming was very, well, charming to both of us.
The second time I was there with a friend, and the step-sisters were in high form that night. It was very funny.
But like the PP said, the wait was horrible. Of all the ADRs I've had over the years, even ones we've arrived early for, I've almost never had to wait more than 15 minutes (and RARELY more than 5) - but both times at 1900 we've waited between 45 minutes and an hour. Sure, there are worse places to wait than the lobby of the GF, listening to the piano and just relaxing in a comfy chair (though this was easier with another adult than a bored child). And it's probably not as likely earlier in the evening. But that was the only negative.
And we have breakfast AND dinner ADRs during this next trip.
