Lots of places to have breakfast, very few that are of the old school Cambridge House ilk.
Except: The coffee shop in the Ohio House Motel, at Ohio and LaSalle.
A little grimy-looking, but don't be dissuaded---it's excellent and cheap ($3.85 for the "Deuces Wild" breakfast special).
Opens at 5:30 am.
See, I'm an idea man, Chuck. I got ideas coming at me all day. Hey, I got it! Take LIVE tuna fish and FEED 'em mayonnaise!
