In hospitals, smoking is confined to certain areas. This is supposed to be backed up by fines. We don't know whether this is enforced.
Comments are welcome.
Tijuana Restaurant Ochoas Av. Not sure about the separation, but this is the first Mexican restaurant we have come across that makes a point of mentioning nonsmoking areas in a prominent way. Happy hour Sunday to Thursday 4-8pm. Live music and dancing. 5 minutes from the border.
