Okay sorry I don't have a different place to suggest, but I just wanted to give my 2 cents. Rainforest Cafe, I thought would be a great place to take my 2 year old last summer....well, they sat us next to the gorilla. When the gorilla started grunting and beating its chest, she FREAKED out. We had to leave. We moved to a different seat, had a bathroom break, but after trying for 20 mintues to calm her down, we just had to leave because she would not calm down. So, the moral of the story is, I still think its a good idea, just don't sit near the gorilla...it can be scary to a 2 yr old.
And as far as Johnny Rockets, I really don't think their food is that good and certainly not worth the price. You want a good burger and fries, stick with Red Robin like you suggested yourself.
Have Fun!
