Er, excuse me barman, I think the barrel needs changing, this lager looks off.

But hold on. These drinks knocked up by bar owner Mustie Hassan might look odd, but they’re actually completely safe and proving a hit with punters at his new Maidstone venue – Nitro Bar.

The bar, in the alley next to Strawberry Moons in Gabriel’s Hill, Maidstone, offers cocktails made with liquid nitrogen, and shisha pipes which allow the user to inhale absinthe fumes.
