Here are some in my neck of the woods. I didn't give descriptions because these shops have websites.

The last one is my LBS. It's Slough's. Located in San Jose, California. George has been in business for a long time. Mostly dealing in newer stuff now but still has beautiful Italian bikes and frames from the 70's. Older campy parts, vintage jerseys and shoes, and more stuff than I could list here.
