There are two Rainforest Cafes on the Disney property, one at Downtown Disney, and the other at the entrance of Animal Kingdom. I've been to both, and since they are both very similar and have the same menu, I decided to condense them into one post.
Name: The Rainforest Cafe
Location: Animal Kingdom, near the gate (there are two entrances to the restaurant, one inside the park and one out, so technically, you can eat here even without theme park admission) and Downtown Disney, in the Marketplace section.
Cuisine: American
Type: Table Service
Good for those who: Want to watch animatronic gorillas and fake rainstorms while they eat. Also, this place is good for people who want a lot of menu options (it has more than any other eatery at Animal Kingdom).
Price Range: Disney lists this in the $$ range, which technically means $15-$35.99 per person. Entrees prices here vary greatly depending on what you order, but average is around $20.
Times: Downtown Disney location serves lunch 11:00am to 4:00pm, and dinner from 5:00pm to 10:30 pm. The Animal Kingdom location serves lunch 10:15am to 4:45pm, and dinner from 5:00pm to 7:50pm. This location also serves breakfast, from 8:30am to 10:00am.
