Mayor Al, “Hot Ham Sandwiches” are definitely a regional specialty of CNY (started at Eddie’s as the story goes, so it may have begun there as a menu quirk) however, I think that “BBQ Ham Sandwiches” are more readily found in the area these days.  Both equally delicious.  Heading up to Rome for a long weekend so I’ll be partaking in some in just a few days!!!
 
Davebassman, a belated welcome to Roadfood!!  That sounds awesome though I’d be surprised if you are able to find poutine in the Buffalo (Western NY) area as it is pretty much a Northern NY (Massena, Potsdam, Malone, Plattsburgh) thing since they are so close to Montreal, the birthplace of poutine.  
I used to work in NJ with a guy who is born and bred NJ all the way.  His family runs a seafood shack on the Jersey Shore in the summer.  He came into work one day and said, “You’re from Central NY, right?  What’s the big deal with these Chicken Riggies I keep hearing about?”  I said, “How did YOU hear about Chicken Riggies?”  Turns out the guy who owns the bar/restaurant next to my friend’s family’s place is from Rome, NY and put some CNY specialties on the menu, including Riggies and he kept bending my friend’s ear to come by and try them!  Sometimes these regional foods we love do end up traveling to the most unexpected places!
