Its finally summer and while the big heat wave has gone, the evenings are just right to sit outside and enjoy the night with some friends and a drink or two. If you are looking for a place to do just that, look no further and head to the Brunel Museum on Fridays or Saturdays. Not the place for a drink? – it sure is. Since the opening of the roof garden on top of the Southern Shaft of the Brunel tunnel, they have been organising Midnight Apothecary.
