Welcome drinks beneath the suspended Lynx helicopter add theatre before guests take their seats.
It’s practical, too: multiple spaces on one site make reception‑to‑dinner flows effortless, the on‑site café keeps logistics tight, and nearby Sloane Square Tube supports low‑impact travel. Add private views or guided tours for a memorable experience that keeps procurement smiling.
