London diners daring enough to attempt the wings challenge at this American-style restaurant will need to sign a waiver claiming they do not hold the owners responsible for any bodily harm that comes to them from participating. The challenge itself is simple: eat 6 wings heavily doused in Naga Viper chili sauce in 10 minutes without food or drink. Once finished, there is another 5-minute cooling down period during which no drinks are allowed. The brave souls who try this challenge must wear rubber gloves while consuming the wings, and if they are victorious, they get their photo forever displayed on the restaurant's walls. FYI, the naga viper chili pepper is 500 times hotter than Tabasco sauce. Not so simple after all...
