There were several Minnie Pearl Fried Chicken restaurants in Mississippi. Two that I can remember were in Jackson, and one was in Hattiesburg.
The two in Jackson were on Highway 51 South near the Jackson Square Shopping Center (across the highway from the Alta Woods neighborhood) and on Ellis Avenue next to the new (then) Krystal.
The one in Hattiesburg was on Highway 49 - just south of Hardy Street - on the west side of the highway on a frontage road.
What I recall about the food was that Minnie Pearl's gave packets of honey to go with the rolls. This was before the chicken places went into the biscuit business. The poster above was also correct in that packets of wet napkins were also found in the boxes.
On the boxes themselves was a brief biography of Miss Minnie Pearl.
The building on Highway 51 was torn down. There is a paint store there now - the store may not be on the exact site of the Minnie Pearl's restaurant - but it is near there.
The other two Minnie Pearl restaurants were both turned into record stores.
Capitol Music (which was located on Amite Street in downtown Jackson) bought the building and opened its second location there. (Later, Capital Music was to open additional locations at Highland Village and at Rankin Square).
In 1972, Ken Clements, Ltd. (originally on Old Canton Road) opened its second tuxedo rental business there. The tuxedo side of the business was called "The Groom's Corner."
Later, that location was closed and Ken Clements, Ltd. moved down the street to the Old Canton Plaza shopping center (near the Balcolny or possibly in the same location).
A sewing machine store opened in the building.
Capitol Music stayed in the builing throughout the 1970s and into the 1980s. Around the early 1980s, Capitol Music lost its lease for its downtown business, and the one on Ellis Avenue was the only Capitol Music left. That building was sold to another fast food franchise - which turned out to be a Mrs. Winner's Chicken.
Capitol Music closed its door, and the building was demolished in order to build the Mrs. Winners. That company had three locations in Jackson - but they only stayed in business here for about eighteen months.
The Mrs. Winners building on Ellis Avenue is now a seafood restaurant operated by some very nice Vietnamese imigrants.
The Minnie Pearl's Fried Chicken locations DID have an unusual design - and they can be spotted from a long way. The Capitol Music used the kitchen to sell the records. The front area was not used, and it was particianed off half-way for the tuxedo business and the sewing machine business. There remained the "window" from which the chicken was passed through to the people at the cash registers.
The Minnie Pearl's Chicken in Hattiesburg was also turned into a record store. I am not sure if it is still standing or not.
