Chicago Style Subs?

I was born and raised in Chicago. After moving to the Twin Cities, I periodically crave Chicago-style food, just like any Chicago native. I have found some great places to get Italian Beef and Chicago-style dogs. However, one of my favorite staples of Chicago food, is the sub sandwich. It doesn't seem like I can find a place in the Cities to get one like they make in Chicago. I'm looking for something like they serve at Fontano's, for any of you that have been there and know what I'm talking about. Awesome bread, tasty meats and cheeses, drenched in Italian oil and vinegar. If anyone has any suggestions, it would be greatly appreciated. Thanks folks!
