Doubt it, many Southern European countries establishments still allowed smoking inside despite the official bans, some with or without measures taken (legally permitted) to mitigate smoke inside them...besides most restaraunts and bars do have outdoor seating and people have no problem sitting/smoking there
Wiki "Portuguese Law 37/2007 governs various aspects of the consumption, sale and control of tobacco in Portugal, and lists a large number of enclosed spaces where smoking is not permitted, including such obvious cases as schools, hospitals and theatres. The law states that exceptions to the no-smoking rule may be made in the cases, inter alia, of enclosed eating and drinking establishments (i.e. restaurants, cafes and bars) not frequented by under-18s if the smoking area is physically separated from the non-smoking area or where ventilation and air extraction systems directed towards the exterior are effective to the point of preventing smoke from entering the non-smoking area, and that in the case of establishments with a floor area of more than 100 square metres no more than 40% (if physically separated) or 30% otherwise may be designated a smoking area. In effect, restaurants are almost always smoke-free as are most cafes whose trade is mainly for food, whereas in bars the law is ignored by customers and bar owners alike. A study published in 2011 by the Ministry of Health showed 90% compliance with the law in establishments with a total smoking ban, but only 50% compliance in establishments where smoking is partly or wholly permitted (i.e., most bars)."
It came into effect on 1 Jan 2008. The Bull, the Luz Tavern and Café Jasmim (Rua Direita) installed extraction systems, permitting smoking inside.
The rest put up mandatory no smoking signs at the entrance so customers knew before they entered whether smoking was permitted indoors or not.
And I did say it was a shame it was not implemented before Madeleine went missing, as it would have meant more people were nipping outside for a smoke.
