80 Standing / Reception

Martha's Bar offers a private sanctuary beneath Williamson's Tavern where vaulted ceilings curve above exposed brick walls, creating an atmosphere that feels both grand and intimate. The space handles everything from corporate gatherings to birthday celebrations, with room for 80 standing guests or seated diners around wooden tables that catch the warm glow from elegant chandeliers overhead. The checkered flooring adds character to this underground retreat, while plush red leather seating runs along the walls, giving groups comfortable spots to settle in with drinks from your own private bar. We've kept the historic architecture intact, those original brick arches and ceiling vaults that make the space feel special, while adding practical touches like air conditioning and reliable Wi-Fi that actually keeps everyone connected. For presentations or entertainment, there's a large screen ready to go, and you're welcome to bring your own music or DJ to set exactly the right mood. The versatile layout works brilliantly whether you're arranging 30 colleagues boardroom-style, setting up theatre seating for 75, or creating a U-shape configuration for 24 participants in more collaborative sessions. Just minutes from Mansion House, Cannon Street, and Bank stations, guests find us easily after work or on weekends. The private bar means no queuing with the upstairs crowd, your group has dedicated service throughout the evening. From buffets to sit-down dinners, we work with you to sort the catering that fits your event. This isn't just another function room, it's a proper London hideaway with centuries of history built into the walls, perfect for drinks receptions, milestone birthdays, engagement parties, or any gathering where you want somewhere with genuine character rather than bland conference facilities.
