Seems I heard something about Chock full of Nuts (huh-huh) opening a place in NY recently. Can't find anything on it, though.
For burgers, I remember that Hayes & Bickford's in Boston had great ones in the mid-60's, especially on Boylston street. For the 4:00 AM drunken crowd, there was always the Waldorf (no relation to the hotel), also on Boylston Street.
Thanks for the great Hopper image. There's a Hopper exhibition at the Whitney right now.
