Fantastic stop! If you don't want to pay thirty euro to enjoy a Guinness "at the source", step around to the opposite side of the block from the tour entrance, climb the stairs, take a seat at the bar (or a table), and enjoy the perfect pint!
All three bartenders were exceptionally friendly and offered advice on my planned itinerary, giving some additional suggestions, and steering me to more local places than what I had planned.
The beer selection is quite nice. Everything you would expect at a Diageo owned pub, and then a few nice surprises. The tap list showed a "coming soon" selection, and I'm sorry I will miss the Pink Gin beer (but hopefully you can enjoy it!).
Pricing was fair, and actually less than some of the other pubs I visited, which was a nice surprise. There is ample bar seating, and indoor and outdoor table seating.
