Jim's isn't much to look at from the outside. The gravel parking lot often has several 18-wheelers parked on the side and everyone else just sort of fills in the other space haphazardly. The sign on the building is not flashy and the surrounded buildings are closed and abandoned.
Walk in, however, and you'rd immediately among friends in a classic diner. The inside is super clean even if it is a bit cramped.
The place is always packed the reason is that the food is awesome. All of the typical breakfast fare done exceptionally well. Next time you are in the area, surely worth a visit.
