My local music store. It's very small and rather crowded, but it has so many wonderful things in it. It has every sort of stringed instrument imaginable: violins, violas, guitars, mandolins, ukeleles, harps, dulcimers, the list goes on. There are also penny whistles and recorders, and probably some other wind intsruments I'm forgetting. There's also lots of wonderful books of sheet music (almost all folk music and jazz) and recordings. To make it even better, the owners' two sweet-tempered golden retrievers are always there to greet customers and be petted. The owners are really nice and helpful and don't make me feel like I'm completely ignorant.
My mandolin. Which I just bought at above store on Saturday. It's wonderful the way I'm able to play for an hour and a half and feel like no time has passed. I also love how I can see hear how much better I'm getting at playing it from day to day.
