M DEN is a private members' club worth its salt, so much so that we've held multiple parties in the Threadneedle street venue. Attached to steak maven Martin Williams' multi-faceted grill restaurants (M), M boasts two separate venues in The City and Victoria - both of which will ensure you a salubrious setting, luscious libations, classy comestibles, and plenty of bells and whistles to boot.

The original M DEN is located in the heart of Bank on Threadneedle Street. Assigned the moniker 'Super-Size M DEN' when it opened in summer 2017, it can pack in a generous number of diners and drinkers. The space features high ceilings from which futuristic pendant lighting descends, with a rotating selection of art adorning the walls, chic billiards and foosball tables, a Belvedere martini trolley, Def Tech 5.1 entertainment system, and, perhaps most importantly, Japanese TOTO electronic toilets. If you look closely upstairs behind a discreet door you'll find 'The Locker Room' - an intimate games room complete with private bar, an outsized television screen, bottle lockers, gaming systems and another foosball table.

M Den Victoria Street can be found in the Zig Zag Building after passing through the Wine Shop. The room is accessed through a secret wall and has a colour palette of chocolate and burnt orange, softly illuminated by feature lighting, smoky wall sconces and a fireplace. The sixty cover bar is perfect for work and play, open until 1am with personal bottle lockers for members, a six seat screening room and access to M's excellent food and beverage offerings. Members will additionally get perks at M Bar & Grill Twickenham, with priority bookings, match day access, a complimentary weekend brunch offering and monthly members events.
