In my Star Wars RPG, there was a bar on Coruscant simply called "The Inconspicuous Spot". No one knew what the actual name to the bar was, because the sign was quite inconspicuous. And the bar was filled with a bunch of low-lifes, all trying to lay low. Since no one wanted anyone to look at them, they didn't look at anyone else. Thusly, anyone there appeared quite inconspicuous.
