The old Blue Boys was directly across from City Hall in what we all called the JEA parking garage, the sandwiches were HUGE. Never really much of a crowd though, but then again this is downtown Jacksonville and Hemming plaza is within site. Perception - Reality.
Ian, who owns The Fox also owns Chomp Chomp downtown, never been to it, but i've heard good things about it. The Fox is a diner, it is what it is, he and the staff do a great job and never try and sell you that they are making Orsay's fare in there, and that is fine. Its great for what it is, a nice local diner. Its as much a part of Avondale as the perception that there is no parking available, EVER in Avondale.
