Lisa samples her first pint of Guinness in the Oxygen Bar - an amazing 360 degree view over Dublin at the end of the Guinness tour.

The Guinness factory tour is possibly one of the best tours I've taken in a long time. There's a clear affection for their brand and history, even if the company is now owned by Diageo, a massive global corporation. Ignoring that fact, it's interesting to see how the company developed and there are a fair few lessons entrepreneurs could learn from Arthur Guinness, even today.
