Owned by the same people that own Rainforest. It will be between McDonalds and Fulton's. I had a sample of a Mushroom Ravioli during the Festival of the Masters and it was good.
http://www.landrysrestaurants.com/ It gives you a list of their restaurants. T-Rex is on there, but no info as to when it is opening. It just says 2008.
