You can buy those buns still in Connecticut. “New England Style” rolls, sometimes called clam rolls.
They’re clam rolls, and they’re still at Friendly’s. Which is in much better health than poor HoJos.
I finally went to the famous Crif’s a couple of weeks ago and yes, the hot dogs are actually worth the hype. I just got the plain Crif Dog, a hot dog that actually has pork in it, but there are many toppings and sides.
If you are visiting NYC, I suggest you go at an off hour. Saturday night is too much East Village scene and Crif Dog is jammed.
