London brewer Fuller's has bought a grade II-listed pub in Hampstead from a private owner for an undisclosed sum.
The deal for the Holly Bush, which has operated as a pub since 1807, was completed on 23 December.
It is split 55/45 in favour of drinks and has received a five-star rating from Time Out.
Simon Emeny, managing director of Fuller's Inns, said: "The Holly Bush is a beautiful, charming pub with lots of little quirks in its personality which have endeared it to its customers over the years.
"Classic wooden floors, etched glass windows, nooks and corners and open fires all come together to make it a real haven from the hustle and bustle of modern life.
"It is just the kind of pub you want to visit after taking the dog out for a walk, or to read the Sunday papers. It has a great reputation for its selection of food, beers and wines, which I can wholeheartedly recommend myself.
"The Holly Bush is a perfect fit with the other wonderful pubs we have purchased this year and I am absolutely thrilled to have been able to add this one to our estate just before the end of 2009.
"Along with The Flask in Highgate, The Holly Bush gives us a vastly improved presence in this terrific part of London."
Previous owner, developer Simon Kirkham, said his main reason for the sale was to concentrate on his new development, the Great Western Studios in London W2.
"I've been here for exactly 10 years and I didn't want to sell the pub to just anyone.
"We had a great deal of interest from a wide range of parties and it was important to not be tempted by the highest price, but to consider the pub's future.
"I feel Fuller's has the experience to nurture the business and help retain its unique character."
Chris Bickle of Davis Coffer Lyons, which handled the sale, said: "This is one of these pubs that anyone who loves the trade would want to have.
"It is absolutely packed with history and character and underlying this is a very successful business with real growth potential for Fullers."
