D3 Collective is a group of companies founded by Des Gunewardena, bringing together a portfolio of distinctive restaurants, bars, and live event venues. The company partners with a range of investors, acclaimed chefs, and leading restaurateurs to create unique, experience-driven hospitality concepts. D3’s current projects include two venues at the Royal Exchange: Engel, a bar inspired by 1920s Berlin, and Jang, a refined Korean Japanese dining destination. At the Grade II-listed Pillar Hall in Kensington Olympia, the group will launch in Spring 2026, Idalia, a grand and vibrant 300-cover all-day restaurant; Pepperbird, an intimate speakeasy influenced by Olympia’s musical heritage and Pillar Hall; and Upstairs at Pillar Hall, a striking 500-capacity event space evolving into a restaurant and bar with live music at weekends.
