One will be located in the South departure lounge, opening in April, while an additional unit in the North landside area is planned for June.
They will offer a busy, cosmopolitan city vibe and serve up beers, champagne, wine and cocktails and breakfast, lunch and dinner.
The bars will also incorporate a tasting table where guests can book wine and cocktail masterclasses and the first will be fitted out next month.
Richard Gill, Birmingham Airport’s head of commercial, says: “We’re committed to providing our passengers with a world class experience and over the last few years we’ve improved our food and beverage offer throughout the airport to offer choice for all our passengers.
“The arrival of All Bar One’s first ever airport bar next year will enhance this even further, giving our passengers and visitors access to this sophisticated Mitchells & Butlers concept, delicious menus and extensive bar choice, all within a lively and chic environment.”
Gary John, property director of Mitchells & Butlers, says the firm is delighted to have acquired the two locations.
Birmingham Airport is the UK’s seventh largest airport, and it handles around nine million passengers a year.
