Your favorite hub/city/town

I was thinking about hub areas in games. You spend a good amount of time in them selling loot, upgrading equipment, talking to NPCs, etc. WoW is no different. Whether you are there for the AH, perhaps you're an RPer, you like the music, or you just like the general vibe of the area.

and as an attempt to create something a bit positive for GD what with class changes coming out and some not liking them... (I know I am a bit sad with WW changes) why not share something positive!

So GD, I ask you, what is your favorite hub area/city/town? My favorite would have to be Undercity. It just has this... feeling. It's dark, it's not pleasing, yet the people there are all messed up and won't judge you harshly, or so I would think. If I am on a horde toon I will afk in Undercity no matter the race. It's hard to describe in words why I like it, but I do for some strange reason.
