FYI, I ate at T-Rex in Kansas City, KS last weekend. I believe it's the first one built (but I could be wrong). My opinion: If you love Rainforest Cafe, you'll love T-Rex. Otherwise, it's just an overpriced and loud theme restaurant. We took our 2 year old son, and truthfully, I have no reason to go back. It just wasn't that cool. The dinosaurs were very loud, drowning out our waiter as he talked to us. We sat next to a giant fish tank, which was cool for about the first 10 minutes. The food was good, but very overpriced ($11.99 for a burger?).
Don't get too excited. Nothing new to see.
