The Red Room
612 Hadley

The Red Room was a prominent early bar in Houston.

But before it at that address was Shirley's Place.
Below from Citizen's News (SF), Feb 24, 1964

Below, early bar listing from the Albatross, 8/18/65, including the Red Room.
I only have data to verify that by August 1965 it was already in business,
though a mention in a Summer 1968 Albatross says it "has always been a
popular bistro since its inception in 1964.

It closed in the Fall of 1974.

  

It is interesting that most of the early ads only display "RR" and not a spelled out name.

Intersting license announcement, did the Red Rooim not serve mixed
drinks prior to 1971, or was some sort of re-licensing required

the next two ads were spread over two pages, so I did three scans of each ad

  

  

    

Above, the Red Room was included in the bar listing of Contact in June 1974,
and was gone by December 1974, replaced by Odds & Ends at the same address.
(I do not have the issues in between to narrow it down more)
