Eat Fish, a Berkhamsted restaurant that is listed in the Michelin guide, has bought Nicholl's Brasserie in Bedfordshire as its second site.
Nicholl's Brasserie in Woburn Village, sits on the banks of the River Great Ouse. The two-storey building can seat 150 people inside the contemporary, open-plan restaurant and another 150 customers outside.
The first floor has the potential for conversion into accommodation.
Vendor Paul Cox, who has owned the leasehold on the restaurant for the past 12 years, plans to concentrate on his event catering business.
The Milton Keynes office of Christie & Co sold the leasehold in an off-market sale. It was seeking £400,000 for remaining eight years of the current lease. Annual rent is set at £50,000.
