Patty and Bun has partnered with neighbours, Kricket to support prison rehabilitation charity, Key4life.
The partnership will see the burger chain collaborate with the Indian restaurant to create their own versions of the same dish, the Jiminy Kricket.
Patty and Bun will offer a cumin spiced lamb patty topped with goats curds, mint raita, slow-cooked lamb raan, wild garlic and green chilli chutney, while Kricket will serve the dish burger slider-style in pao breads with two per portion.
Both restaurants will offer the dishes in their White City Television Centre restaurants from April and lasting the entire month. As much as £1 will be donated from the sale of each dish to Key4life, who will use the money on rehabilitation programmes for young men in prison and those who are at risk of going to prison.
