Although I am seriously allergic to tobacco smoke, I see no rationale any more for a ban on smoking in Oak Park restaurants. Public attitudes have changed, and the restaurant industry has changed with them. Any number of Oak Park establishments are smoke-free and will remain smoke-free not because they are forced to be, but because they have chosen to be.
I won't patronize a restaurant that is smoke-laden, but I also don't patronize restaurants that are too loud, overpriced or have poor food. I have no difficulty finding Oak Park restaurants that are smoke-free, not too loud, not too expensive and offer good food.
Twenty years ago smoking bans might have made sense, because non-smokers had no alternatives, but that is no longer the case. We have excessive governmental regulation of business already without imposing solutions to what aren't even problems. There is no constitutional right to have every restaurant in town operated to suit one's personal preferences. Market forces have created an ample range of alternatives to suit anyone's tastes.
