Gramophone

If you're looking for a CD, particularly an older one, Gramophone is a good place to go to. It is not very big but the staff are more than willing to help you look for the disc you want. If you're not sure of what you want, it is also a good place to browse the neatly categorized sections while enjoying the music that is playing in the background. Prices are about the same as other stores such as HMV, so there's no real distinction there.
