If you are looking for a fun experience in coffee shops, I think, Mellower Coffee, is worth the visit. Their unique concept of serving coffee is totally cool. The Sweet Little Rain is a huge cup of Americano coffee with a ball of cotton candy suspended on the top. The steam of the hot coffee melts the sugar cloud which then rains down on the drink.
Just be prepared to get a little messy because the sugar droplets can also land directly on the cup and on the saucer.
