He later worked at the Oberoi Grand (Kolkata) and took over the running of Gharana, a restaurant specializing in royal Indian cuisine.

Their discussion on applying French cooking techniques to Indian cuisine led to the establishment of Singh’s first restaurant in London.

[6] Singh co-founded The Cinnamon Club in London in 2001, marking his first venture into modern Indian dining in the UK.

Singh collaborated with former rugby union stars Jason Leonard, Martin Offiah, Lee Mears and Nick Easter to raise funds through an event called Scrum Dine With Me.

[19] Singh has worked with Action Against Hunger since 2002, and for the past four years has been hosting an annual Diwali Charity Event in their aid.

[21] Singh works with The Prince's Trust charity, Mosaic Network,[22] which aims to inspire young people from deprived communities to realise their talents and potential.

[23] In 2008, Singh was approached by Virgin Media to create the world's hottest dish to commemorate the launch of their Bollywood movie channel.

Singh responded by saying that although his dish made it into the Guinness Book of World Records,[24] there is no real way to measure whose curry is the hottest, as it depends on the taste buds of the individual eating it.
