According to the 2006 anti-smoking restrictions, smoking was NOT allowed in

A tough anti-smoking law has taken effect in Spain.
    The ban — one of the strictest in Europe — outlaws smoking in all bars and restaurants. Smokers will also be prohibited on television broadcasts, near hospitals or in school playgrounds.
    The law tightens anti-smoking restrictions introduced in 2006.
    The anti-smoking rules introduced in 2006 outlawed smoking only in the workplace. It let bar and restaurant owners choose whether or not to allow it. Most chose not to impose any ban.
    Only large restaurants and bars were obliged to provide a smoke-free area.
    Now, hotel, restaurant and bar owners have said they could face a 10% drop in trade with the new rules, The industry has already seen a sharp fall in sales due to Spain’s economic problems.
    But doctors argue the new legislation will help smokers give up.
