This is a throwback to what music stores used to be 20-30 years ago.
Walls and floors lined with gear, new, used, valuable, professional, cheap, beginner. Everyone working is knowledgeable. Prices are usually fair, not usually steals, and they are willing to negotiate. Repairs on damn near everything are done in house. Come in with a question and you might get a 2 hour answer, or shown how to do something free.
You wont find the kid with the hair gel that knows nothing about music but can hand you the $100 WalMart-ish guitar from behind the counter. You will find some comparably cranky old guys who actually know the stuff and will sell you a real guitar.
