Se-Port Deli Boon (or Boone?)

My "kids", who are now in their 20's have been going to Se-Port Deli and getting the "Boon" since their days at Gelinas Jr. High.   It comes with a huge cup of ice tea, which no one can replicate and everyone loves.  When they come into town its' the first meal they want.  Here's a picture from their Facebook page.
