Since moving to Boston from Ohio several years ago, I've been intrigued by the differences in Chinese takeout/delivery places. French fries on the menu was a surprise, for one :)
But the one that baffles me is in the 'chop suey and chow mein' section -- many places say they offer "Chicago or Subgum style" for 50c extra. A Google search turns up a lot of confusion. Can anyone clear up what these styles mean?
