Hookah
It sounds to me like you might have to rethink your concept. In my hometown, there was a place similar to what you are describing....they offered food, atmosphere, and of course, hookahs. But smoking is smoking. And I don't think that what you are wanting to do is in line with what is permitted, unfortunately. But maybe this is an opportunity to expand on the idea using different angles (leaving the hookah smoking OUT of the equation). What if, instead, you opened a little cafe that had floor pillows, low tables, morrocan embellishments, food, turkish coffees, wine, low lighting, music, bellydancers....maybe you could burn non invasive incenses that are reminiscent of the hookah tobacco, so that you maintain ambiance. Also, think of your market....if the town has implemented non smoking (which they did in FL too...at first it was WEIRD, but after a while, people got used to...and even appreciated...it) policy, then, it is probably going to stay that way for a long time. Maybe you could write it into your biz plan to bring in the hookah if the ban is ever lifted. Just be careful if you decide to go more cafe than lounge.....do your research and make sure a niche restaurant like that is likely to survive in your area.
