Tiki bars and restaurants were a big fad beginning after World War II. They've had ups and downs in popularity, but they have persisted through the decades. You can still find them today, and they may even be staging a comeback. Nearly every state in the union has at least one Tiki-style bar or restaurant, featuring sweet, fruity cocktails and Asian & Polynesian food with a bit of Mexican and Caribbean thrown in occasionally.
There are several websites devoted to Tiki food and culture. See these for starters:
Critiki - Find a Tiki-themed bar or restaurant near you!
