Guinness apparently tastes better in Ireland and nowhere better than the place where it’s brewed. Having never been a Guinness drinker myself, I didn't have much to compare it with, but after a hearty lunch, I struggled to finish the complimentary half-pint we received at the end of the tour. Fortunately, there were plenty of people with me who never refuse a free drink.
A stiff drink may have been better at the start of tour, which was unbelievably dull. Our group had possibly the world's dullest tour guide, who showed no enthusiasm for the subject and was lacking in the legendary Irish wit.
The gift shop was great for all those obligatory (clichéd) Guinness souvenirs for the folks back home.
