Then I moved. First to the central Illinois, then NW Pennsylvania. It seems that a hoagie to these people is 2 slices of bologna on a hotdog roll.
Last week I was in Waterbury, CT for a job and got an Italian Combo "Grinder" from Nardelli's. Good bread, generous amount of meat on it... I was in heaven.
Another great East Coast deli sandwich is a "Corned Beef Special". In parts of the Midwest, they've never even heard of "Corned Beef Specials".
