Crossroads Bar on Newington Green closed on Wednesday after being asked to vacate its premises.
The north London bar has become known for its carbonated cocktails in recent years, with leaders Bart Miedeksza and Valentino Girotto recently publishing a book on the subject.
On Friday the Crossroads leadership team announced that "with a heavy heart" they needed to "permanently shut the bar down on Wednesday" and "vacate the premises with immediate effect".
The statement continued: “While we regroup and put our thoughts and ideas in order, you’ll hopefully still see us here and there, with pop-ups or guest shifts. Please reach out if you have a space that needs activating! We believe that our contribution to the hospitality industry is not yet complete.
“We would also like to take a moment to thank our magnificent team for unrelenting support during this weird time. Some of us have now been left without a job and if your bar team needs brilliant people please reach out and we’ll put you in touch.
“At Crossroads we have a saying that every challenge presents an opportunity. We’ll do our best to make the most of it. It’s not a goodbye.”
