It'll be on at 7p here, tonight, with a repeat later in the week. I see our PBS is also showing a "pub crawl" on March 2:

Historic Pubs of Dublin - Take an exciting and visually stunning tour of Dublin's most notable historic pubs, as well as the many places of interest that surround them. Pulitzer Prize-winning author Frank McCourt (Angela's Ashes) serves as tour guide, providing valuable insight into Irish culture and history - and the significance the Irish pub plays in both areas. This program teaches future travelers how to make the most of their visit to Dublin.
