Re: Creating a hookah bar
yeah, plantlife is a must, palm trees if you could get that going, give the place some atmosphere.
Leather couches, as Jimmy said, are ideal. Vinyl if you don't want to spend the money, but leather is best. Stay away from ANYTHING that might get burn marks or stains.
As far as drinks go, arabic tea is a must, hot and iced. Chai would work well too. Try to keep a middle eastern or indian theme throughout the place, authentic but modern, you know?
