Ok, here goes:
I remember Jack's Deli (now the Fish Store) on Bayport Ave and Montauk Hwy and Make Someone Smile flower shop, on Montauk near McConnell Avenue, is where the Fish Store first opened
Then there's Ed's Deli -- it's still a deli but you'll find Ed and Wayne at Blackbird's Grille these days.
What businesses do you remember? What's there now? Share your knowledge and let's see who has the best recollections.
For example, anyone remember where the Bayport Post Office was before it opened on Montauk Highway?
P.S. Attention Local Historian Gene Horton: You're too knowledgeable to play along :)
