I kind of hate choosing a chain over one of the local bike shops, but I've got nothing but great things to say about Erik's.
I've brought my bike there many, many times. Service is outstanding--outwardly friendly, very upfront about cost and repairs you may need. They'll also let you purchase parts elsewhere and install them for you--which happens to be pretty awesome.
I brought my bike in last week for an estimate--it needed a new outer chainring, cassette, and bike chain (not surprising considering I got 3,000 miles out of it). They gave me a list of parts--which I bought myself for much less--and then installed everything for me.
The best part? Well, if you're with the UW in some way, shape or form, you get HALF OFF LABOR! I saved a boatload going with Erik's, and the work done was top notch. A+ all the way.
