I went to the Rainforest Cafe for the first time in 2001 while I was in Orlando. What I liked about it the most was whenever a volcano would rupture or if someone ordered a volcano dessert, everyone would scream, VOLCANO... That was so fun.
I had a chicken ceasar salad. My mother in law had a hamburger and she said it tasted just like steak. Everything was great.
The staff was very polite and pretty speedy with the service even though the restaurant was jam packed with visitors.
Reservations are not necessary but I do recommend it if they allow it. The place is almost always packed with people and the wait is a little long.
All in all, my visit there was fun and filling.
