A cold food display unit includes a well defining a receptacle, an insert positioned within the receptacle, a refrigeration system, a first cooling air discharge, and a second cooling air discharge. The insert is positioned within the receptacle to form a first cooling air flow path and a second cooling air flow path. The refrigeration system includes a cooling air outlet positioned within the receptacle to provide cooling air to the first and second cooling air flow paths. The first cooling air discharge discharges a first flow of cooling air toward the second side of the well, and the second cooling air discharge discharges a second flow of cooling air toward the first side of the well.
