We really like the one on S. Lamar. I think it would be okay for a 2-year-old, provided that it's not too crowded and that you supervise. Some of the jumpy things would be too big and hectic for a 2-year-old, but there are a couple that are specifically geared for younger ones.
For us, it's all about timing with bouncy houses. I think 2 year olds love them as long as they aren't being bounced around/bumped in to by kids twice their size. I have never been to that particular one bit my advice would be to go early before it gets crowded.
we go to the one on s lamar. when school is in it's not too crowded in the mornings. my babysitter esp takes my 2 yr old (along with another 2 yr old) and they have a ball.
