That's assuming smokers go to bars just to smoke, not to drink or eat.

I have friends with small restuarants in NYC who actually removed tables in order to not have to ban smoking. They considered their afterwork smokes & cocktails regulars pretty much $acred ca$h cow$ who showed up rain or shine, and year round.

I would think it would depend on the demographics. If most people don't smoke, the non-smoking bars would get most of the customers. The smoking regulars might be a very small, though dependable, percentage. I don't know if this has been tried anywhere, but it would be interesting to know if the smoking bars were able to attract enough business.
