Incredibly Meangingless Question

"Grandpa" Al Lewis — best known for his roles on The Munsters and Car 54, Where Are You? — used to have a restaurant in Greenwich Village in New York.  It was called either Grandpa's or Grampa's and it's not there anymore.  But which was its name and what was its address?  I was by there once and I think it was on Bleecker, but for reasons too boring to explain, I'm trying to find its exact location for someone.
