A new all-day restaurant concept, Subsūme, will open in Covent Garden this October, bringing European dining inspired by Japanese culinary techniques and hospitality to the heart of the West End.
The 70-cover restaurant will occupy a two-floor, 2,700sq ft site in Sussex Mansions on Maiden Lane, creating 30 front- and back-of-house roles. Subsūme is the debut concept from sibling founders Agastya and Varuna Singh, developed alongside concept director Ben Floyd, Founder of Lumiere Consultancy, and creative agency 48.1.
Subsūme was born in spring 2025, when the founders travelled through Japan to understand what makes the country’s hospitality so exceptional – and what they could bring back to London.
The discovery that shaped the concept wasn’t traditional Japanese cuisine, but European dishes reimagined by Japanese chefs. Familiar dishes, executed with extraordinary precision, reverence for ingredients and depth of craft, felt entirely new. Rather than creating another East-meets-West fusion concept, the founders were inspired by the idea that Japanese values of provenance, simplicity and technique could elevate European cooking into something genuinely distinctive.
The journey also shaped Subsūme’s hospitality philosophy. In Japan, omotenashi is more than service; it’s a cultural value centred on anticipating guests’ needs before they’re expressed and giving generously without expectation of return. That spirit of generosity now underpins every aspect of the restaurant, from the food to the guest experience.
