We have tried ESPN Zone, Rainforest Cafe, and Naples.
We loved ESPN Zone. The food was delicious and the kids loved all of the big TV's. Fairly reasonable for DLand prices too.
We really liked Naples. I had pasta, but DH had the pizza and he liked it. Maybe not somewhere I would be DYING to eat again, but it was good, if a little overpriced (like you expect in DLand).
Even with kids, we really aren't fans of Rainforest Cafe. Sure the decor is fun, and the kids love it, and their food is always so basic, it's fine, but we don't like the adult options at all, while we felt like ESPN Zone food was worth the price, I always feel like I'm way overspending for nothing at Rainforest. If you decide to go, just know you're doing it for the kids and the ambiance, and not the food!
