For the past three years, Kronos Food has held a free gyros day in the middle of summer to support the Fisher House Foundation, which helps builds comfortable lodging for the families of hospitalized military personnel. The sandwiches are given away at four Kronos Gyros and Cafes at highway oases in the Chicago suburbs and more than 50 participating restaurants. Consumers can visit and download a coupon for the sandwich. In return for the free sandwich, Kronos Foods asks consumers to donate and help support the Fisher House at the Edward Hines Jr. VA Hospital in Hines, IL.

In addition to other promotions for the foundation, employees regularly volunteer when the Glendale Heights, IL, company serves free dinner to the families staying at the local Fisher house.
