Why It's Amazing: It used to be a Victorian toilet (they retained many of the original features such as the 1890s porcelain urinals, which are now tabletops) but don't let novelty fool you into thinking they are not serious about coffee. Coffee beans come from King's Cross Caravan Roastery and milk from the Ivy House Farm in Somerset.
What to Drink: A "piccolo," which sits somewhere between a macchiato with extra milk and a small latte.
Perfect Pairing: Start the day with a muffin filled with maple cured bacon, Swiss cheese, egg and spinach - a healthy version of an egg and bacon McMuffin.
Know Before You Go: Ironically, there are no toilet facilities.
