This building, on North Main at the intersection with Sunset Drive, was obviously a fast-food joint of some kind, but I'm not sure which one. I believe at one time or another, a commenter said it was a Church's Chicken, but the street numbers don't match for that. If anyone can identify it, I will change the post title to reflect that.
Currently, it's a TitleMax/CheckMax which seems to be one of those chains favoring old fast-food locations. Interestingly, directly across the street is another "hermit crab" operation, a Family Dollar which moved into the old Eckerd's.
UPDATE 15 July 2010: OK, based on the comments (and confirmed by the 1998 phonebook), this place is identified as a Long John Silver's and I'm changing the post title accordingly.
