The folks at Exposition Park Cafe are donating 15% of all food and drink sales after 4 p.m. today to the NTAF South-Central Stem Cell Transplant Fund. The nonprofit provides support to uninsured patients who have undergone stem cell transplants or suffered serious injury. Tonight’s profits will go to local patient Anita Mester to help her cover medical expenses from a recent stem cell transplant. Tonight’s happy hour specials are $3 domestics and $4 you-call-its. If you’d like to help the Mester family, you can come sip some happy hour drinks…seriously now, how’s that for philanthropy? Just think of it as goodwill by the glassful.
