You may not know you like science fiction books but you will after visiting this place. First and foremost, Sam (I'm assuming he's the owner) has an encyclopedic knowledge of SciFi and here's why that's a reason to get a book here. Tell him what type of book you're looking for and he'll find. "Sam, give me one with family drama, sort of like 'Long Day's Journey Into Night' or something like that. And damned if he doesn't get the right book. I've done this several times with him and he always finds the right book. Sometimes I'll go in and just ask for great sci-fi that he likes. He'll make a detailed recommendation without being preachy and lo and behold, I've got another favorite book. The man doesn't miss.
Second, the store is really pretty. Small location but easy enough to browse. The specials in the middle table contain some surprising great titles in terrific condition.
You may not know you're a sci-fi fan. But visit this store. Let Sam know what you're interested in. Browse a little. You'll find something and it'll be wonderful.
