I'm a little unusual in that I can't eat Disney food because of my dietary restrictions - Disney provides special pre-packaged food that fits my needs (they get frozen meals from an offsite vendor and reheat them in the kitchen), and it's pretty much the same food everywhere. So for me, all that matters is the atmosphere. Which is why I really like when they have that discussion in the dining reviews. The discussion about the food is interesting (and often hysterical), but never relevant to me. But when they talk about the restaurant and overall experience, that tells me whether or not this is somewhere I should consider getting an ADR. So for me, I have to pose the question backwards ... is this somewhere I would eat despite the food?
For me, that's Be Our Guest because I absolutely love the castle, and we've always had great service there. We also had a really nice breakfast experience at Cinderella's Royal Table on our last trip (but that's insanely overpriced).
When I'm looking for new restaurants to consider on my next trip, I like to read/hear reviews where people keep going back even if they don't enjoy the food because that's a restaurant that I may want to try out.
But I'm weird and I know that this doesn't apply to most people.
