Baltimore's Terrific Judaica Book and Gift Store!.
I'm an out-of-towner (i.e. not from Baltimore) and found this store and the people who work there just terrific. I was stunned to read the 2 reviews below (written on the same day) by Byron S. who obviously must have some ax to grind (or woke up on the wrong side of the bed).
It's a great place to shop for gifts, books, and all kinds of Judaica. The staff is polite, friendly, and helpful. Prices were reasonable as well.
