I just happened, accidentally, upon the "Long Beach" page of a website that claims to know where the party spots are around the world. Of course, none of us trust that a website subsisting wholly on advertising dollars would bother, or even care, to stay updated on the dynamic party scene in any big city, but I was surprised to see that the "Gay Bar" section mentions three establishments, including Christy's on Broadway.
I go to Christy's five or six times a year because it's good and close by. Some hounds put it on the top of their LB recs, and I can understand that, too. But I've never heard or thought it to be a "lesbian bar," as the website states. It has a kind of "adult" ambiance, I would say, but I've seen plenty of families and grannies and mixed couples.
My point: if you tend to be dissuaded by things like this, don't be. Christy's is about the food (Italian-ish, and a pretty good wine list), and much less about the scene.
