With a total of 56 pubs around the nation, All Bar One is a well-known pub chain in the UK. The chain is owned and run by Mitchells and Butlers plc, a business that, up until 2003, belonged to the Six Continents conglomerate. In Sutton, Greater London, the first All Bar One pub opened, launching a company that would go on to dominate the UK hospitality sector.

Female friendly' was the idea behind All Bar One, a novel notion at a time when many pubs and clubs were seen as forbidding places for single women. The business is renowned for its spacious open floor plans, huge glass fronts, and light, airy interiors, all of which add to a warm and welcoming ambiance. In 1994, Amanda Wilmott created the concept after researching other female-friendly pub businesses like Pitcher & Piano and Slug and Lettuce.

All Bar One has experienced consistent growth and expansion throughout its history. When Bass, the parent firm at the time, established the first bar in December 1994, it had 15 All Bar One pubs. The network has expanded to 46 bars by 1999. The chain is now present throughout the UK, from Aberdeen to Central London, displaying its broad appeal and ongoing success.
