For $30, today's side deal gets you a four-pack of tickets to Milwaukee Irish Fest (up to a $60 value). This year's Irish Fest runs August 19–22 at the Henry W. Maier Festival Park. These tickets are valid for ages 12 and up; children under 12 are free.

The 30th-Anniversary Irish Fest celebrates an entire weekend of Irish music, dancing, food, shopping, and other cultural activities rooted in the Emerald Isle. The festival's mammoth collection of live music at more than a dozen stages provides Celtic harmonies at every corner, such as the ruminations of Gaelic Storm, who is playing three times at the festival, including at 8:30 p.m. and 10:15 p.m. on Friday, and at 7:30 p.m. Saturday and Sunday on the Miller Lite Stage, and the bagpipe masters of Red Hot Chili Pipers, playing four times throughout the weekend.

On the south end of the grounds, chat with Irish authors and peruse authentic knit handcrafts, clothing, and artwork at the Cultural Village. Those with young, aspiring Dubliners can camp at the children's area, which features a Lego/Mr. Potato Head tent and a mini-golf course. Hungry festival-goers can fill up on the offerings of dozens of food vendors, with plentiful helpings of beef stew and baked Irish oatmeal cookies, among many other Irish favorites.
