Lunchbox is, very literally, your friendly local record shop.
They have a healthy collection of new and used, cd and vinyl, and always more than a handful of well marked local artists. That is not to say that they are huge, because they are definitely not, but they make every square foot of that store work towards their music-y goodness. Oh, and anything they don't have, just ask and they can probably order for you.
They are always more than willing to let you hear a new album on the store stereo before you buy it and if you happen to lose your phone in their parking lot they will totally help you look for it. I have bought everything from used Pat Benatar vinyl to a delightfully electronic Matmos cd there (and I didn't even feel like they were judging me for the Pat Benatar!).
Their prices are a bit higher than you might find at some chain store or the used section of Manifest (used cds start around $6, new stuff flirts with a Jackson unless it's on sale) but the eclectic selection and wonderful local-ness of Lunchbox make it worth the extra coin.
