Kristen,
Yes, Crystal Palace is decidedly FAMILY oriented. While the food is good, the restaurant is a bit chaotic and noisy, and Tigger, Winnie the Pooh, and others bumping around certainly make it even more so.
As for more "adult" selections like you have listed, I have a few others that I can add that you might consider;
- Jiko (delicious, exotic elegance)
- Boma (A buffet, but a wonderful one with inventive Indian and African inspired selections)
- Sanaa (A great, and overlooked, restaurant. The shared items are phenomenal!)
- Flying Fish (best fish on property)
- Hollywood Brown Derby (great salad)
- Le Cellier (Cheddar Cheese Soup. Enough said.)
Now note that the Hollywood Brown Derby, Flying Fish, and Jiko are all pretty expensive (or 2 table service credits each on the Disney Dining Plan).
Now if you write me back about some of your likes/dislikes, I can recommend SEVERAL great other choices, from gospel brunches to fun dining without a big show (or big price tag), to elegant and romantic escapes. Just give me a few road signs, and I will map it out for you!
Have a magical (and delicious) vacation!
