Located on New Cross Road between the train stations, you will find a charming little barbershop named Unique Hair Technique by Patrick & Son. The clean exterior made up of a white front with red detailing contrasts the busy interior decorated with souvenirs that customers bring back from their holidays to gift their favourite barber. Inside, there are racks filled with holiday memento keychains, but the highlight of souvenirs is the salon’s left-hand wall. The entire wall is plastered in bank notes from all over the world, including 5 Jamaican Dollars (£0.03), 1000 Drachma (£2.62) from pre-Euro Greece, and 10 Zambian Kwacha (£0.61). Pat, the owner tells us that there are currencies, old and new, from at least 30 different countries.
