Just back from Orlando and wanted to offer my followup to our visit there. Bottom line: park food was better than we remembered, our few restaurant visits were mostly underwhelming.
In the Magic Kingdom we had lunch at Columbia Harbor House, just outside the Haunted Mansion, and the tuna salad sandwich was remarkably ok. The toast wasn't too toasted but the sandwich was really quite acceptable. Similarly, dinner that same night in Tomorrowland (the big counter place) was a bbq pork sandwich that was quite acceptable. Rave-worthy, no, but compared to what I remembered from MK, I had no problem with either of these items, they weren't even ridiculously priced.
We ate at the French place in Epcot, not the super expensive one but the one right on the main drag that faces the lagoon. It was ok. Nah, it really wasn't that good. It wasn't horrendous/inedible but no, not very good. Bland onion soup, boring croque monsieur, odd creme brulee. Woudn't recommend it.
We also ate at Universal Islands of Adventure, a counter service spot back near the cartoon area (by the Dudley-do-right water ride) and that also was surprisingly ok. Had spaghetti with meatballs, the meatballs were not cringeworthy as I feared and the spaghetti was actually al dente.

We also had a Cinnabon at Universal, please don't revoke my LTH membership status.
Grownup dinner (once) was at Moonfish, which was the overwhelming suggestion from a number of different sources. We were underwhelmed. It was pretty pricey, nothing was all that special, and the dining room was so behind on reservations that we witnessed people leaving and literally shouting at the hostess about the horrible wait and the food not being worth the wait. Really strange, considering how highly it came recommended.
Also had a quick lunch at Flippers, a local chain of 5 or 6 spots that do handtossed pizzas and pastas. It wasn't bad, a really tasty Ken's caesar dressing that I haven't been able to find in the grocery store, and decent if not stellar pizza.
Orlando remains NOT a culinary destination. LOL
