It is possible to cross Dublin without passing a pub.
In Ulysses, James Joyce mused that “a good puzzle would be to cross Dublin without passing a pub”. No-one’s really sure if it was possible, and Dubliners have always felt proud that it was not straight forward. The traditional Irish way to ‘solve’ this puzzle is to walk across Dublin, and call into every pub in the way and have a pint. This way you never actually pass a pub.
