The permit calls it a 22,000 square foot restaurant attraction. There isn't a mention of retail, but I'm sure they will have a gift shop like Trex and Rainforest. For a size comparison T-Rex is 30,000 square feet including retail space and has seating for 600. It won't be as big as TRex but could be big enough to seat 450 to 500 which would put it on scale with Raglan, HOB, Planet Hollywood and Bongos. In other words pretty darn big.
I wouldn't go to Florida and stay at the beach and eat at Red Lobster either when I could get fresh caught seafood all over the place. Further inland like Orlando could be a different story...nah, I still wouldn't go
