Speciality Shops are often different from normal shops due to the specialising in a particular product. Twinings for Tea or Forbidden Planet for Comics are examples.
Speciality Shops can also be a type of shop that tend to be unique and one of a kind. These type of shops tend to be a joy to wander around and have staff with extensive knowledge of the product.
These kind of shops offer a more personal approach rather than the sometimes soulless high street shopping experience.
Notable London Speciality Shops are Rough Trade, Paul A Young, The Tea House, Les Senteurs, Forbidden Planet, Foyles, L Cornelissen & Son, James Smith and sons, Twinings, Tatty Devine
