Long before nursing school I actually worked as a "Safari Guide" (server) for Rainforest cafe LOL. Funny thing, I made more there waiting tables than I do as a nurse, but I digress.......
In my opinion, as a fromer Landry's employee, the best meals are/were:
Pastalaya (really great if you like spicy food, can also be made with rice instead of pasta, turning it into Jambalaya)
Pot Roast...sounds weird for RFC but was always really well received by my guests
Nile's Shrimp Enbrochette....these are the bacon wrapped crab stuffed shrimp mentioned in a previous post; they use to be available on a combo plate, not sure if that is still the case.
For Dessert: The Volcano! Loads of chocately goodness complete with a sparkler (unless that's against fire codes now).
Hope this helps! When you go, be sure to ask about the source of wood for the dining chairs, how the sky above replicates a night sky in the rainforest, and who receives the money from the Atlas fountain.......there really is more to this place than your typical touristy restaraunt if you take the time to enquire!
