Colonna & Small's is a specialty coffee shop in London that pulls espresso and brews filter coffee from beans sourced around the world. It serves milk drinks such as flat whites and lattes alongside drip coffee, and the acidity and roast character differ from bean to bean. For both espresso and filter, customers choose among several beans, and the barista explains each bean's characteristics. Filter coffee is the order to place when you are not in a hurry.
