My local prepared ahead for the ban with a very pleasant decked area outside. I have noticed that there are very few people inside and its quite busy outside, whether that will change in the winter I don't know. Even non smokers are sitting outside - it certainly can't be the sunshine - as its been mostly rain
They have redecorated inside, and it looks very good, they even provide little stickers that say just nipped out for a smoke, so that no one will remove your drink or nick your seat while you are having a smoke.
There is a really good atmosphere amongst the smokers, joking about being even worse social lepers.
