Harden's says

Atop The Old War Office (OWO) in London, this summer 2024 arrival is a second rooftop venue in one of London's landmark building under the direction of sushi master Endo Kazutoshi (the other being at the former HQ of the Beeb, see Endo at the Rotunda). Especially for this mega-luxe hotel, the launch pricing is perhaps surprisingly (and sensibly) approachable: it is not a tasting-only format, with an à la carte with mains from £25-£25, a lunchtime three-course menu for £55 per person and the tasting menu here being £130 per person, and not just dedicated to Sushi but with a number of dishes, for example pork ravioli or Turbot with smoked sabayon, that would not look out of place in a Modern European restaurant. So the spin is very different from his W12 HQ. Planning a special meal? The venue includes a private dining room set in one of the OWO’s historic turrets!

“Wow, this is exceptional!”“super views of the Houses of Parliament” are not the only reason to visit the OWO’s rooftop Japanese yearling, which is also “a true foodie experience”. Under the direction of renowned chef, Endo Kazutoshi (of Endo at the Rotunda, see also) the style has evolved away from the Japanese-Italian fusion fare with which the venue was launched to now focus on the “top Japanese cuisine” for which Endo is known (although puddings such as White Chocolate Tart or Strawberry Mille-feuille are resolutely westernised): “the sushi and sashimi is amazing and there are other awesome small plates” and robata dishes. The menu is à la carte, although there is also a ‘Taste of Kioku’ option for £150 per person. “Service is both professional and friendly”. Top Tip – “great value lunch” (three courses for £55 per person); and “a perfect place in the summer with the outside terraces” (for which there is a separate more abbreviated menu).

Summary

Atop the Old War Office (OWO) in Whitehall, this summer 2024 arrival is a second rooftop venue in a London landmark to be under the direction of sushi master Endo Kazutoshi (the other being at the former HQ of the Beeb, see Endo at the Rotunda). Especially for this mega-luxe hotel, the launch pricing is perhaps surprisingly (and sensibly) approachable: it is not a tasting-only format, with an à la carte menu featuring mains from £25-£25, a lunchtime three-course menu for £55 per person and a tasting menu at £130 per person. It is also very much NOT solely dedicated to the sushi for which Endo is renowned, but includes many modern European dishes: for example Pork Ravioli or Turbot with Smoked Sabayon. So the spin is very different from his W12 HQ. Planning a special meal? The venue includes a private dining room set in one of the OWO’s historic turrets!

Summary

From the all-star team behind Endo at the Rotunda – another Japanese-influenced rooftop venture: this time a 60-seater on top of London’s splashiest hotel opening in decades, complete with outside terrace. Kazutoshi is backed by Misha Zelman, the man who created the likes of Burger & Lobster and the Goodman steakhouse chain.

For 34 years we've been curating reviews of the UK's most notable restaurant. In a typical year, diners submit over 50,000 reviews to create the most authoritative restaurant guide in the UK. Each year, the guide is re-written from scratch based on this survey (although for the 2021 edition, reviews are little changed from 2020 as no survey could run for that year).

What the Newspaper Critics are saying

The Times

Giles Coren couldn’t get a booking at Tollington’s, the north London chippy makeover that’s causing a sensation in hip foodie circles, so he had to settle for a meal at a new place from the “great, glorious and beloved Endo Kazutoshi” of Rotunda fame, at the hotel owned by the Hindujas and full of “ridiculous International Superwank restaurant offerings”.

The food was, of course, delicious – most notably a “rich and fatty/salty, utterly sublime” crouton piled with chopped raw fatty tuna and a splodge of aged caviar.

But, said Giles, … “Everything was beige, it was £540 and everyone was on their phones. Like everyone, all the time… scrolling while they ate. It didn’t make one feel, you know, special.”

“Endo is a genius, no question,” he concluded. “But this is not the sort of place that does it for me. I just don’t warm to the ghoulish transience of a megahotel and the tax exile citizens of nowhere such a place attracts.”
