Tom and Beth Kerridge, owners of the Michelin-starred Hand & Flowers in Marlow, are to open a bar a two minute walk away from their restaurant with rooms.
The drinks-led venue called Claytons, on the site of the former Claytons Lounge nightclub, will serve a large range of bar-style food including slow-braised dishes served in small stone pots for between £4.50 and £5.50.
All the food will be cooked at The Hand & Flowers.
While the menu will feature some 25 dishes, including home-cured salmon with brown bread and confit of cod with chickpeas and chorizo, Tom Kerridge emphasised the new project would be a bar rather than a restaurant.
"There'll be no waiters, no maitre d', you'll order from the bar, the food's all very simple, and you don't have to eat at all. If you just want to come in for a drink, that's fine," he said.
The Claytons, which is a joint venture between the Kerridges and Hand & Flowers employee Laura Aherne and her partner Lennox Leach, will have a 2am licence on Friday and Saturday nights, and will feature DJs playing chilled-out tunes at the weekends.
"It will be for people who want to stay out and have a drink without having to go to a nightclub," added Kerridge.
"It'll be a nice place where you won't get beaten up or knived at two in the morning."
Kerridge is hoping to open the bar, which is leased from the Henley-based brewery Brakspear, on 24 January.
