I don't think anyone has mentioned the Australian chain, Max Brenner. Actually I think it is based in Israel, but it has a substantial Australian presence. There is also one in Singapore. Max Brenner serves food, but the chocolate desserts and drinks are the main draw. They have dark and white hot chocolates. They also have a drink called the suckow (sp?) where you melt chocolate over a little burner and mix with milk. Delicious and unusual. They also have a wide variety of chocolate cakes, brownies, cookies, etc. I have not really seen a restaurant like this anywhere else. Located in David Jones Dept. store in Sydney, Manly Ferry Pier, Double Bay, and Singapore's Esplanade Performing Arts Complex (the big durian).
