444 Porter Avenue
This Burger Chef in Biloxi was a 60s style building. It closed in the early 70s and the building was demolished.
The 1970 phone directory for Biloxi and Gulfport shows the address as 444 Porter Avenue to be exact. It may have been torn down more recently, but it survived well into the 1980's as the Jiffy Jac Drive-In, with walk-up service and outdoor seating only. The food was mediocre at best however.
