I just learned that on September 28th the voters in Canton Zurich approved a ban on smoking in restaurants and bars. (I could not find any information on when the ban goes into effect.)
This ban strengthens the ban on smoking in public places which went into effect on July 1st.
It is a huge relief as I was very concerned about bringing Global Baby back to Zurich, where 29% of the population smoke like fiends! Now we need not fear taking him out to restaurants and other public spaces.
