And Chicago is playing catch-up with New York.
A proposal under consideration there "calls for a ban on smoking in restaurants, offices, banks, bingo halls, movie theaters, lobbies, gymnasiums, shopping malls, pool halls, bowling alleys, waiting areas of public transit stations, grocery stores and sporting arenas, among other venues.
"Among the few exceptions? Homes (as long as they don't double as licensed child care, adult care or health care facilities), cars (as long as they're not owned by the city) and bars (as long as they're not attached to a restaurant)."
Another version would extend the ban to all bars.
