All Bar One, Leicester Square

All Bar One Leicester Square occupies one of London's most recognisable addresses — directly on the square, steps from the West End's theatres and cinemas, with the energy of central London's entertainment district as a permanent backdrop. It's a venue where the location does significant work: guests know exactly where they're going, transport options converge from every direction, and the surrounding neighbourhood turns any event into a night out.

West End Location, Leicester Square Energy

The terrace is the draw that most Leicester Square venues can't match. Ninety outdoor seats overlook the square itself, giving summer events and evening drinks receptions a setting that borrows atmosphere from one of London's busiest public spaces. Inside, two floors of colourful, contemporary interiors spread across a generous footprint — bright enough for daytime meetings, atmospheric enough for evening celebrations.

Space and Scale at All Bar One Leicester Square

With 380 standing capacity inside and a mezzanine that functions as its own semi-private zone for 180, the venue handles everything from intimate team drinks to large-scale company parties. The mezzanine's own bar and mix of seating and standing areas make it a natural breakout space during bigger events — or a self-contained hire for groups that don't need the full venue.

The Mitchell & Butlers operation means reliable service at scale — two bars keep drinks flowing, in-house catering covers everything from sharing boards to set menus, and the events team has the infrastructure to handle corporate bookings, birthday celebrations, and everything in between. Cocktail masterclasses and bottomless brunch add built-in activity options. Leicester Square tube is adjacent, Piccadilly Circus and Charing Cross are within easy walking distance, and the late licence runs to midnight with extensions available.
