Re: Hookah Bar
There are countless variations. There is no single answer to your question.
There are some that are classic hookah lounges. No entertainment, no alcohol, and no gimmicks. Perhaps some coffee and some food. Focus on conversation and relaxation
Others are just bars that serve hookahs along with other tobacco products.
Still others are more modern lounges that are filled with music and TVs. Little to no focus on tradition and more focus on the younger crowds. Mostly college kids.
Some are restaurants that offer hookah.
That is just scratching the surface of the answer as well.
