On the first Tuesday of each month from 12–1 p.m. during the fall and spring semesters, there is a "Pet Hugs" therapy dog event to provide stress relief to students.
[citation needed] Lower Sproul Plaza, directly west of Upper Sproul Plaza, is the location of numerous small musical and cultural performances and is surrounded by numerous brutalist-style 1960s-era buildings owned by the ASUC, including the Martin Luther King Jr. Student Union to the east,[1] as well as the César E. Chávez Student Center to the north[2] and Zellerbach Hall to the west.

The Martin Luther King Jr. Building is home to the Campus Living Room, Pauley Ballroom, Cal Student Store, Berkeley Art Studio, Multicultural Community Center, Creative Lab, a coffee shop, a food hall, and many student-run services such as BicyCal, Blue & God Yearbook, SUPERB, ReUse, Open Computing Facility, and more.
