If you like tourist traps, then this is the place for you. I've been to a number of Rainforest Cafes in different cities, and they are all roughly the same.
Views are kind of neat the first time or two, with the rainforest-like atmosphere and large fish tanks. There is a variety of food options similar to your typical American chain restaurant, but the prices are hiked up due to the "uniqueness" of the atmosphere. I've tried a number of food options, and nothing has really stood out to me as something I'd just have to go back for.
I'd recommend going if you've never been to one, or if you have made it a goal to visit this restaurant in every location possible, but otherwise I'd pick something where the price better matches the food quality, or try some local fare.
