Popeye's used to be one of those places that had better quality and flavor profiles than most fast food chains and very respectable portion sizes.
There's some debate as to whether corporate pressure from head office has decreased portion sizes and reduced the weekly sale offerings which have turned away many long time customers. So now, we're paying higher prices for roughly 1/2 of the food given before. In feeding a family of four, I shelled out over $40 without any leftovers.
Over the years, service quality has declined as some of the employees have gotten too comfortable in their jobs. Though the food is fresh, delivery time is normally very long, and some front end staff bill for unavailable/items not received. If service quality improved a bit, I'm sure they can restore some of their customer base.
