Swap the Guinness for Erdinger this fall at Oktoberfest Dublin, one of the many beer festivals happening around the Emerald Isle. Free for all attendees, the ode to Bavaria features a mouthwatering menu of bratwurst, spätzle, Burgundian ham and other traditional German dishes. Visitors eager to stay late are required to purchase a wristband, guaranteeing a hearty meal to help soak up the wheat beer in the wee hours. One euro from every wristband sold helps disadvantaged children from Dublin -- an excuse in itself to raise a glass.
