Uhm, totally not a place where you can go and relax, unless you're with a group of friends. There's just this "run-down, seedy, unkempt and dangerous" vibe you get when you approach The Ruby Room.
I'm no chicken sh*t. I can deal with dive bars. I like them, actually, but not when the little hairs on the back of your neck stand up. If The Ruby Room were in another location - perhaps in the neighborhood of Modified Arts and Lost Leaf - it would be a sure-bet.
The decor can feel very vampire-like, though, with dark, red walls, low lighting and the naked women on the wall, looking down at you. Plus, they now serve absinthe. (As for their beer selection? Meager, at best.)
Again, if you're going out with friends, this place could be fun. Otherwise, don't bother.
