Clyde's Drive-In is a small chain of historic burger drive-ins in Michigan. The first Clyde's was opened in 1949 by Clyde VanDusen, a Michigan Tech student. The original location stayed open until 3 a.m. and featured servers on roller skates.
Clyde's Drive-Ins are located in Sault Ste. Marie and Manistique. A third location in St. Ignace, Michigan, opened in 1971 and shares the name. It is independently owned. Former locations include Rudyard off the I-75 373 exit.
Clyde's motto is "Wear a Smile", and the outlets are known for offering a Big C, a 3/4 lb burger, and the Big B. burger. In addition to the famed burgers, the St. Ignace location offers hot dogs, fried shrimp, fresh whitefish, perch, and grilled cheese sandwiches made with Velveeta.
