At the top of our list would be the Columbia Harbour House in MK. Yep, go figure. Our absolute favorite lunch throughout WDW, with the best tuna sandwiches EVER!
We also love the 50's Prime Time Cafe. My husband would be happy if I booked every meal there.
My husband loved Fulton's (DTD), but the kids and I didn't care too much for it. We all loved Raglan Road.
CHH is one of our favorites too! We enjoy the fried shrimp platter or fish and chips, and sitting upstairs, near a window overlooking the Haunted Mansion. Very relaxing.
