#1) Blue Bayou that is inside Pirates- make reservations and traditionally I have booked the last reservation of the evening and have waited for about 45 minutes AFTER my reservation time to be seated. When I'm there in Feb I will try a new strat. and book an early dinner to see if it cuts down the wait time. TRUST ME it is worth the wait!
#2) Napa Rose in the Grand Californian
#3) Village Haus in Fantasyland (Next to Pinocchio's Daring Journey). Great for a quick bite and has a good varity.
#4) Carnation Cafe in Main Street. GREAT for lunch! They have a soup and sandwich combo that is like $10 YUM! Get the pretzel bread sandwiches! Ask to sit in the sun you by pass the waiting line and the sun will move and then you will be in shade in no time.
#5) La Brea Bakery cafe for dinner and Express take out side first thing in the AM for breakfast. The baked goods are brought over fresh baked from the flagship restaurant on La Brea BLVD in Los Angeles in the AM daily. They taste best first thing in the AM. I worked there while in college when it opened and met the owner several times, she is wonderful and so is her food! The coffee is Peets and the espresso is Illy YUM!
#6) Jazz Kitchen in Downtown Disney
#7) Catal in Downtown Diseny
And those are my favorites
As far as eating in DCA, I usually just get grab and go there, but there is a cool bread bowl place, Boudin I think, around the Warf area.
