I go every now and then, and will second that you are paying for the space. As many people will tell you, if your on the
DDP I think you're better off paying cash, 2 credits is a lot for this place. It is overpriced, but what isn't? I wouldn't say the food is bad, but don't expect the same quality you'd get at Cali Grill for the same 2credits.
I've never been to lunch, but would like to try that next as the menu does look better.
IMHO, Breakfast is the best in terms of food quality, worst in term of value (especially if you use credits, its way expensive)
At least with dinner you get more for you money, but the food CAN be lackluster compared to many other places.
So, I know I will continue to go because I love the experience and think it's worth it. I like the food, but go in knowing it's not going to be the fine dinning experience of my trip.
If you're more concerned about getting great food for your money and don't care about the dinning experience, maybe this isn't the place for you.
Also note, the characters don't spend a ton of time at the table. If you wouldn't mind missing the castle experience, try a meal in Norway. The food is excellent and you still get the princess meet and greet!
