The New Zealand-born chef opened the site with general manager Michael McGrath in Marylebone in 2001, where it made an impact with its small plate, fusion dishes and one of London’s first brunch menus.
But the pair have decided to shut the restaurant at the end of July to travel and pursue other projects.
Gordon and McGrath say in a statement: “Having The Providores and Tapa Room in London since 2001 has been absolutely brilliant! But, we've decided that it's time to close the doors, and so at the end of July we'll do just that.
“We couldn't be more proud of the restaurant we have created: we have had a huge amount of fun, employed and mentored hundreds of talented staff and introduced the flat white, Turkish eggs, small plates, brunch and no reservations to the UK dining scene.
“We’ve been an unofficial NZ trade showroom showcasing NZ food, wine and drinks, a NZ way of service, and a NZ vibe. We’ve hosted wine dinners, chocolate dinners, book launches, weddings, and have had regulars stand by us us from day one. But, we have decided we want to pursue other, personal projects and travel and relax after working our socks off for 18 years.
“It's been an incredibly tough decision to make and we are obviously sad in many ways, but this is the right decision for us personally and we want to go out on a high. We hope to see as many of you as possible over the next few weeks for grilled scallops and sweet chilli sauce, and a glass of NZ sauv blanc or three.”
Gordon ran London fusion restaurant Kopapa with Adam Wills from 2010-2016, and is involved in Crosstown Doughnuts. He is also behind New Zealand restaurants The Sugar Club in Wellington and Bellota in Auckland.
