We did Rainforest Cafe and T-Rex on our trip and liked them both pretty much equally for food. Very similar menus. Not the best food we had, but far from the worst. Probably preferred the atmosphere in T-Rex, and both can be very loud at times.
The best thing about T-Rex was the crack-your-own-geode in the shop. Kids loved it. Range of size/price geodes to buy (about $10 up), and you get to crack it open yourself with a rock splitter.
