Minneapolis hosts its 50th St. Patrick’s parade along the refurbished Nicollet Mall—a 10-minute drive from pubs including Kieran’s, Keegan’s, and The Local, all brimming with Guinness and pipe bands—while St. Paul’s vehicle-minimal (and kid-safe) march down Kellogg Boulevard celebrates year 51, continuing a tradition of literally painting the street green, handing out buttons for charity, and crowning Ms. Shamrock before she embarks on her own float. At the capital, once known for its Irish immigrant population, hop the many pubs: Casper’s and Runyon’s Nook, the Dubliner, Emmett’s Public House, O’Gara’s, the Liffey. There’s no wrong turn.
