Go hungry and get the volcano nachos. That should be enough to fill you up, as well as a few of your friends. Wait to order entrees because I find myself full before they arrive everytime.
Watch the show because it is really entertaining. I don't know that I really understand the guys on stilts coming out, but I liked seeing them nonetheless. The woman who slides down the volcano and lands in the margarita glass is classic. Drink heavily for an especially good time. This place has a ton of stuff going on.
There is a gift shop with all kinds of Jimmy Buffett items for sale. This is a fun place to poke around while you are waiting for your table. The location of this restaurant is across the street from Caesar's Palace in the Flamingo Hotel.
