What must I simply drink at the Tonga Hut N. Hollywood?

I know what to drink at Tiki Ti. I know what to drink at Bootlegger's Tiki in Palm Springs. I know what to drink at the Bali Hai SD. I can make 50 authentic drinks or so at home.

BUT WHAT MUST I DRINK AT THE TONGA HUT?

Do they have a secret menu? Specialty drink el fantastico? etc.?
