The Norwich Playhouse Bar has a covered terrace that directly outside the bar. It also has many covered tables and a marquee within the garden.  I'm petioning for the area directly outside the bar to be smoke free as there are plenty of other spaces for the smokers to sit further away from the bar doors.

The Glasshouse in Norwich has moved their smoking area away from the doors so I'm sure a progressive bar like the Playhouse could do the same.
