Off topic a bit, but if we're talking about restaurant diversity, I'd love to see a Melting Pot at Disney Springs. Seems like a perfect place for it. "Fun" interactive concept, high price point, accommodating to families, fairly "safe" food choices. I think it would be wildly popular - particularly if there were some Disney-themed menu items.
The time it takes to eat dinner there is pretty slow, though. Disney restaurants specialize in getting you in and out in 45 minutes to an hour. A 2 hour meal at $130-200 per table is not profitable enough to put in a high traffic area like Disney Springs.
