Seattle bike shops

As I mentioned in a previous thread on Boston, my DH wants to buy a bike in the US to bring to Chile. He just confirmed that he will be attending a conference in Seattle next month, so he would like to start looking and ideally buy his bike there, but still have Boston as a backup plan if it doesn't work out. So... Can anyone recommend shops in Seattle? The conference is at the convention center, so he will presumably be in that part of town. Thanks!

Here's a not-too-old thread that might have some places to start.

Thanks! That thread looks excellent--just what I need.
