Where was the Two Pigs Meat Market?

It was somewhere on Northern Boulevard, I know that much.  It's important because it belongs on the National Register Of Historic Places thanks to the father of the solid body electric guitar, Les Paul.  On January 14, 1951 Paul and wife Mary Ford recorded "How High The Moon" in their home studio at the Two Pigs Meat Market using multitrack recording techniques that Paul had pioneered.
The song became a monster hit and multitracking became the standard approach for recording just about every kind of music thereafter. Rock & Roll, Blues, Jazz, Gospel, Classical, you name it -- there's a little bit of Jackson Heights in all of them.

I don't know if this helps, but I have read an interview with Les Paul, where he mentions living at 81st Street and Roosevelt Avenue and another where he mentions living in the Electra Court Building, and that he had a studio in the basement.  Could the Two Pigs have been at 81st and Roosevelt?
