Don,
I don't know if this is Monte's or not...

Phone Books: 1945 shows:
Montero F Liquor 251 Bridge........56
In the yellow pages, there's nothing under Liquor Stores, Cocktail Lounges or Clubs. Montero F is listed in the yellow pages under "Beer Parlors".

1951 has the same listing in the white pages, but no listing in the yellow pages.
