It did not take long for the fried chicken sandwich to go from a quiet ubiquity to something louder and more ethereal, an idea that simmers, waiting to get picked up by just about anybody. Students of these types of sandwiches, once they have made their way through the fast food wars, will eventually find their way to something called “Hot Chicken,” an idea that historicizes itself by tracing its origins back to an 80-year-old restaurant in Nashville that now invites contemplation from bloggers for major magazines. More locally, the idea had been pitched by restaurant consultants to a developer who had leased the spot of a small, shuttered pharmacy on Wyckoff Avenue, where he dreamed of selling food there instead.
