Restaurant SixSeven

What Restaurant SixSeven does

Restaurant SixSeven (legal entity: Sixseven, RCS Luxembourg, VAT LU33000784) operates a single rooftop bar-restaurant at 103 Grand Rue, Royal Hamilius, Luxembourg City, occupying the 6th and 7th floors with a panoramic terrace at 35m elevation. The venue serves refined bistronomic cuisine curated by Chef Alexandre Delamarre together with pastries and a weekly Sunday brunch by Pastry Chef Margaux Escafignoux, and operates seven days a week with continuous service (12:00–00:00 Mon–Thu, 12:00–01:00 Fri–Sat, 11:30–23:00 Sun). Beyond the core dine-in experience, the business sells gift cards via the Zenchef storefront, offers takeaway click-and-collect, and accepts reservations and partial/full venue privatization (rooftop, dance floor, private 7th-floor salon) for corporate seminars, birthdays, and private parties.

The technology stack is entirely vendor-provided. Zenchef is the joint data controller powering online reservations, at-table payment, gift cards, click-and-collect, customer reviews, and the website itself; Amazon Web Services (AWS Europe) hosts the website; Google supplies Analytics, Maps, and Recaptcha; Meta (Facebook/Instagram) and X/Twitter provide social integration; Waze powers navigation; and Tarteaucitron handles GDPR cookie consent. The website is localized in 12 languages (FR, EN, ES, IT, DE, PT, RU, CS, JA, ZH, NL, EL) and conforms to WCAG 2.1 Level AA and the European Accessibility Act.

The revenue model is purely transactional F&B plus ancillary fees from event privatization and gift cards. Customer segments are diversified across general diners (primary), corporate/business clients, private event hosts, and a niche pet-friendly dining segment — but all revenue is generated through a single physical venue. Payment rails include Apple Pay, Google Pay, Ticket Restaurant meal vouchers, and major cards. The company is privately held with stated share capital of €100, no disclosed external funding, no parent company, no M&A activity, and headcount of 27.
