Of the Landry's Restaurants....Yak n Yeti was far and away the best. Rainforest Cafe was better than T-Rex as well.
Our last experience at T-Rex might have been tainted because our kids were a little scared at first (not scared at Rainforest Cafe, though), but the food was really not good. My twins who would eat Kraft mac and cheese every day (don't judge, I do at least buy the organic version and they eat fruits and veggies) would not eat the mac and cheese there. The kid pizza was not as good as Lean Cuisine, the adult steak was Applebee's (definitely not even as good as Longhorn or Outback), it just was not good and really loud. If you do go there for the atmosphere...stick to the fried food, that food was okay...just don't expect anything amazing.
