The bar will serve a range of drinks made using Fever-Tree mixers, with all proceeds to be donated to charity Malaria No More UK.
Each beverage will be priced between £5.50 and £6.50, the same amount it takes to deliver one mosquito net to a mother and her child in an area affected by the disease.
Tonic water was once used to treat malaria, as quinine – which comes from the so-called ‘fever tree’ – is a natural anti-malarial.
The pop-up, which will be open from 12pm till 10pm, is part of Fever-Tree's broader campaign for World Malaria Day, which fell on Monday (25 April).
To mark the occasion, the brand has released limited edition metallic bottles featuring Malaria No More UK's logo. Stocked at Tesco, Waitrose and Sainsbury’s stores, 10p from every bottle sold will go to the charity.
Saskia Meyer, marketing director, Fever-Tree, said: "Quinine is integral to Fever-Tree as one of the key ingredients in our tonic waters, and it has long been associated with the fight against malaria.
"We are very pleased to be supporting Malaria No More UK as it continues to fight, treat and prevent this disease which impacts on communities in some of the countries where we source our ingredients."
James Whiting, executive director of Malaria No More UK, added: "Our work with Fever-Tree is a great example of two like-minded brands putting a shared goal at the centre of a partnership – to end malaria for good. Fever-Tree is a valued malaria business champion, and I can’t wait to get my hands on some of their limited edition tonic."
Fever-Tree celebrated its 10th birthday last year with gin safaris and pop-ups throughout the UK.
