Jersey Mike's coming to Da Metrys...

Ok, so of the big chain sub shops, where does everyone rank them? I like Firehouse, Jersey Mikes, Jimmy John's and Lenny's as well. But ranking them would be tough for me because I like certain sandwiches at each. Subway is ok, but I would look for any other before going there. None of them hold a candle to a good poboy though. One I have heard is really good, but we don't have here yet is Potbelly.
Lenny's has one of the best Philly's based off of all these chains IMO and the chicken salad is always great.
