Debbie,
There are a number of places that can provide the blue "brain remover". We first assembled these one "hazy" afternoon at the Palapa two years ago. (The Palapa however does always have the required blue additive.) Perhaps the most practiced would be BC's. Either Ernie or Mar'ceo are VERY adept at preparing this, although they will both giggle and smirk while doing so.
On ice or up---
Equal parts: (Generally 1 1/2 shot each
Gin (Tanq or Bombay are best)
Vodka (the better the better)
1/4 shot or so of Blue Curacao
Ernie has informed me of a recent visitor who drank the evil thing on a Friday from 10 a.m. to 5 p.m., and actually survived to tell about it.
Hope you guys have a great time.
