Find out how the black stuff is made, try some Guinness-flavoured food items, learn how to pour the perfect pint, hang out on the amazing branding and advertising floor, then get a pint on the roof overlooking the city. Guinness is good for you.
If you're a whiskey fan it's probably worth a stop and guided tour of the Jameson distillery, which has been running since 1780. As well as the standard tour you can get involved in some premium whiskey tasting, take part in a whiskey blending class or cocktail making class, or even a cask draw experience where you can drink whiskey straight from the keg. Oaky!
If you want to go further afield this is an amazing place to visit, full of bohemian characters, nice vibes, great bars and cultural experiences. Also some amazing food. If you're planning to see some of the country you could do much worse than to head here – and then take a drive west along the coast and around Connemara national park.
