A store that sells only one thing is broadly called a severely specialized store or a one-item shop or one-item purveyors. When that single product is unusual, quirky, or humorous, the specific term is a novelty shop. Other examples of novelty shops include Barn the Spoon (wooden spoons), Just Bulbs (light bulbs), or Ant Store (ants).

If anyone has some time, please send me photos of unusual spoons (they don't have to be just wooden).
