Small is beautiful. One established idea strikes me in Perth : many of the great names or good brands actually have a small "homelike" outlet for tourists to visit. There is usually a little cafe for the tourists to rest and many samples for them to taste. The decorations are usually well appointed and attractive. Everything is neatly arranged and cleanliness is top notch. This is a sustainable and intelligent way of doing business.
It is so delightful to visit Mundo Delight! The nougats are fantastic and it is worth buying a few packets home.
