Some places my family enjoys...
In or near the Magic Kingdom -
Crystal Palace - Pooh & friends character buffet meal in MK.
Kona @ the Poly.
'Ohana @ the Poly, breakfast with Lilo & Stitch.
Chef Mickey's @ the Contemporary.
In or near Epcot -
Coral Reef in Epcot - one entire wall is an aquarium.
Le Cellier in Canada.
Teppan Edo in Japan... My boys (ages 8 & 11) favorite restaurant at WDW, but not sure how convenient it would be with a baby.
In or near Hollywood Studios -
Si-Fi Dine-In in DHS. Sit in cars at the drive-in movies.
Cape May @ the Beach Club. Character at breakfast, seafood for dinner... a nice boat ride from the Studios and a great way to check out some other resorts.
Animal Kingdom -
Yak & Yeti in AK.
Boma @ Animal Kingdom Lodge. Buffet and, again, a great way to check out the resort.
The character breakfast, (the restaurant location has changed since the last time we ate there.)
Downtown Disney -
We're trying T-Rex (for the boys) on our next trip.
