Heck yes I do....
The Baltic Room - This is pretty much the Minc of Seattle & my favorite dance venue. They usually play all types of electronica from house to dnb to downtempo & sometimes hip hop. But I'd check the website to see what's going on for a paticular night.
For other types of venues that have electronica events:
