I went to the LA Artwalk, in downtown LA last Thursday. If you have not been to this, it is definitely worth checking out.
The vibe is great, the art is varied. There was some quality art there. I went with another friend, (something I recommend, as the area is a litle dicey). we got a late start, so we just barely scratched the surface, but if you plan to go down there you should check out Bert Green Fine Art.
Someone else blogged about it here in greater detail. And there are pictures.
