The 50-cover restaurant and 15-cover bar, called Hawkyns, will open on 15 January with ex-Benares chef Ross Bott as head chef.
Launching in partnership with The Crown Inn owners Old Amersham Hotels, Kochhar's new venture - named after East India Company's Sir William Hawkyns - will serve classic British dishes featuring 'subtle accents' of his own culinary heritage.
Kochhar, who runs Benares, Sindhu and Indian Essence in the UK, said: "I’m incredibly excited about the opening of Hawkyns. This is going to be my first restaurant offering a modern approach to traditional British cuisine. It’s something I’ve always wanted to do”.
Dishes on the menu at the restaurant, situated within the 38-bedroom coaching inn, will include Scallops with leek terrine, Chicken tikka pie and Hawkyns Fish & Chips.
A spokesman for Old Amersham Hotels said: “We are delighted that Atul has agreed to partner with us at The Crown Inn. It is going to be a very exciting time for us all and we know that our guests will be delighted."
As well as his three London sites, Kochhar's restaurant empire includes in Lima and NRI at the Bandra Kurla Complex in Mumbai; Benares in Madrid and Rang Mahal in Dubai. The chef also operates Sindhu restaurants on two P&O Cruises ships.
