I am 60 years old and had never been to a hookah bar. My college age children socialize at hookah bars much like my generation socialized in a drinking establishment at that age. My son, daughter, and her BF treated me to my first hookah bar on Fathers Day. The bar had an outside patio with tables and chairs like a restaurant. It was a nice summer evening and a very pleasant experience.
I don't know what the hookah flavor was and my kids didn't remember what they had ordered. The cost was $10 per group. The device had something like a large jar of water that the smoke was filtered in before it was delivered via a long plastic hose which was passed around the table. Everyone had their own sanitary tip, much like the vape shops use at their flavor sample bars.
The place was well populated by small and larger groups of customers. As this was in a University area, it was a younger crowd. The hookah reminded me a lot of what I experience with my personal vaporizors. Smooth, cool, flavored smoke/vapor. From what I understand, the flavored tobacco is soaked in vegetable glycerin and vaporizes into a vapor/smoke from the heat of a burning coal, then is filtered through the water bottle.
