Sonic in Cambridge closes its doors

The Sonic in Cambridge has closed its doors. Cones and chairs block the driveway, with signs reading “CLOSED: We apologize for any inconvenience. This location is CLOSED and will not be reopening. Please visit for information on other SONIC restaurants in Minnesota.” Sonic opened in Cambridge in August 2009 and at that time had 55 part-time employees. Photo by Elizabeth Sias
