Jim Patrinos bought the business in 1974 and re-opened in 1975 after minor modifications to the existing property. With the business flourishing and the original location expanding to 24 hours, Jim decided to open more locations. The second Primanti Bros. location was in Oakland near the University of Pittsburgh. Business took off with hungry students and doctors in the area, so expansion was on the horizon again, adding Cherry Way (downtown Pittsburgh), South Side, Market Square and, in time, Three Rivers Stadium.
