MILWAUKEE (CBS 58) -- St. Patrick’s Day celebrations are underway across Milwaukee, but at County Clare Inn & Pub, the festivities come with a meaningful mission.

The pub is hosting a three-day St. Patrick’s festival featuring traditional Irish celebrations like the Blessing of the Shamrock, authentic Guinness pours, live music and expanded space with a large tent starting Saturday.

On Sunday, the celebration turns toward giving back. For the second year in a row, County Clare will host a St. Baldrick’s fundraiser to support childhood cancer research.

Volunteers shave their heads, beards, and mustaches in solidarity with children undergoing cancer treatment. Organizers say the emotional event brings the community together to support families facing childhood cancer.

The festival continues through St. Patrick’s Day on Tuesday, March 17. Stop in for a breakfast or any time of day for a traditional Irish meal.

The Inn upstairs still has limited availability between now and St. Patrick's Day.
