For a great tour, and some free samples head to the Jameson Distillery in Dublin. This is less popular (and hence less crowded) than the Guiness Brewery Tour, but a lot more fun and laid back!!

The self guided tour includes displays on the history of Guinness and of Guinness advertising. You can see the video of every Guinness add ever made and before long you will feel the need to head upstairs for your free pint in the Gravity bar that has the best views of Dublin on offer.
