My favorite footlong coney is Big Ed's (the last remaining location, at 122nd & N. Penn.

The Sonic ones were decent (but I always substituted sliced cheese instead of the grated stuff that tasted fake) before they came out with the new and improved one and I don't think they are better at all (haven't tried the 4 specialty ones, but my mom really liked them).

Disappointed with Freddy's ... very average taste and over priced.

Only time I get Coits is when they run a half priced special on them and unfortunately, their "brick type" chili is very greasy and doesn't agree with me.
