There's quite a few threads reviewing TRex, so you can search around and I think you'll find a lot of different answers. Yes, it is just like RFC, but with Dinosaurs, but VERY cool!
Definately worth checking out!
I'd say we did not care for the food as much as RFC...
we had the quesadillas, and they were just ok, not too flavorful.
We also had the chicken sandwich in the fried pizza dough, and we didn't care for it, but I think it was just personal taste. It was really spicy which we didn't expect it to be. Our service was okay.
It was probably our least favorite meal of our trip, but glad to have the chance to see it.
My problem with our dinner was that we were seated in the Ice Cave room, which is REALLY cool, but the blue/purple lights gave me a really bad headache, as I get migraines and the light was not good for me over time.
I had a feeling about this when we were seated and should have asked to be moved.
The meteor showers are cool too!
I'd go to look through it or have an appetizer if we go again, but that would be it.
Have fun!
