Things I like about my LQS:
1. Friendly, knowledgeable staff.
2. Kids' play area
What I wish they had more of: Modern looking prints, like Amy Butler. A lot of what they have isn't really my style, although I always find SOMETHING to take home, so maybe it's not as bad as I make it sound, there.
I also wish they offered "Mini classes" that only lasted an hour or two. I could fit those into my schedule a lot easier.
