The Rainforest Cafe offers a desert called the "VOLCANO" which is a huge mound of fudge brownie, chocolate ice cream, hot fudge, and whipped cream then topped with a lit sparkler. There is enough to feed three or four (we share this between three of us). If you have 8 to feed just get two of these deserts. Also (saving the best part for last) they make a BIG DEAL in the restaurant everytime one of these deserts are ordered. Your server will go screaming through the dining area..."V-O-L-C-A-N-O"!..."V-O-L-C-A-N-O"! and then all the other servers will start to scream the echo of this as well!

Order and enjoy!
