Had my first one at Danny’s in 1967.
It made a lifetime impression.
I’d guess that’s about when I had mine. I turned 8 in the summer of 1967, and I recall everyone in our family (except for my dad) being crazy about Danny’s Hoagies. We’d eat them there in the parking lot and try to watch the movie next door at the drive in theater. We lived in Brookline, and it was a real treat to drive out to South Park and see the buffalo.
There was a pizza parlor down the street from Danny’s called Beetos, or something like that. That was our favorite pizza, though hoagies were always the number one food if you had the opportunity.
