Classic Music Store
I go there to get my guitar strings and such, but like any great music stores in the area, you can also just hang out and try out a guitar off the big wall. It is a great way to try a new ax without all the guilt associated with buying a guitar you will only use once or twice a year.
They also have keyboards, drums, wind and brass instruments, they do repairs, and they give lessons.
Don;t be afraid to talk to the staff they don't pressure you to buy anything.
