- Not to be confused with the Port of San Francisco bar.
In 2285, Doctor Leonard McCoy visited this bar to hire a transport ship which could bring him to the planet Genesis in the Mutara sector. He found someone, an alien, but was stopped and arrested by a civilian agent. (Star Trek III: The Search for Spock)
Background information Edit
Although the bar was never named on-screen, the description of several costumes describes the location as "San Francisco bar".   Another unnamed San Francisco bar was attended by Kirk in Star Trek Into Darkness.
The bar was constructed on Paramount Stage 9, on the set that was formerly the location of the sickbay biobeds that appear in Star Trek II: The Wrath of Khan. It was described as consisting of "seats built into the wall encircling the room. By one corner stands a semi-circular table; inside it there is room enough for one man to stand." (Starlog #80, March 1984, p. 45)
The script described the bar as "a crowded, smoke-filled watering hole of the twenty-third century, filled with a smattering of civilians, Starfleet personnel, and visitors from strange and far-off civilizations. It does not have the bizarre qualities of the 'Star Wars Bar' which is across the street."  Indeed, the idea was more than a mere script reference, and was under actual consideration for the film. DeForest Kelley described the scenario thus: "What we wanted to do is open that scene outside, and have McCoy on the sidewalk, where he would naturally encounter other aliens and people from other planets. As he enters, he stops and looks across the street, to a 'Star Wars Bar!' Once, the Lucasfilm people were all there, and we all talked about it. But they would have had to do a whole rerigging of the set and it would have been a whole big deal. But that's what I wanted to see. I think that would have been wonderful and I wish we have had done it." (Starlog #87, October 1984, p. 20)
The bar was featured in scenes 79-83 of the film. According to the above-mentioned script, there was an alternate scene, in which several stunt performers appeared. This is supported by a costume worn by stuntwoman Jean Coulter, who doubled Sharon Thomas  , and the appearance of stuntman Tom Morga.
