Judge Jr. was the nomes de plume of one Norman Hume Anthony, who spent quite a bit of time in Frank & Jack's according to an article from TIME magazine from June 19,1939.
Apparently, Norman was still the editor of the Judge in 1927 when Here's How was published...he was fired in 1930 though and spent "several months biting his nails" in Frank & Jack's speakeasy.

A famous Frank and Jack's speakeasy, which I think we can safely assume is the same establishment, was described in Michael Batterberry's “On the Town in New York” as follows:
More typical was Frank and Jack’s, a jolly place where there were generally a hundred people jammed into a tiny kitchen barely large enough to hold three tables. Among those struggling for air and room enough to laugh might be Jimmy Durante, Pat Rooney, or Peggy Hopkins Joyce. It was Frank and Jack who perfected the gambit of getting rid of one drunk by asking him to assist another out the door.
