About Whole Venue
100 Banquet
250 Standing / Reception
Two private bars across historic floors transform into your personal party space when you book the Whole Venue at Williamson's Tavern. This former home to London's Lord Mayors welcomes up to 250 guests for standing receptions or 100 for seated celebrations, with Mansion House, Cannon Street and Bank stations all within easy walking distance. Our ground floor features the main bar area, where dark wood furnishings meet festive bunting strung between traditional fixtures. Groups naturally gather around the grand wooden bar, drinks in hand, while others settle into comfortable seating areas for catch-ups. Downstairs, the Cellar Bar reveals vaulted ceilings and exposed brick walls that create an intimate atmosphere, perfect when your party wants a change of scene or quieter conversations away from the main festivities. The venue flows brilliantly for celebrations. Wedding parties love how guests can move between the two distinct spaces, corporate teams appreciate having room to mingle after presentations, and birthday groups enjoy claiming every corner as their own. Our projector handles speeches and slideshows, while proper kitchen facilities mean hot food arrives exactly when you need it. Outside, our courtyard catches those wanting fresh air between drinks, particularly popular during summer parties. The combination of indoor and outdoor spaces, plus those two separate bar areas, means your event never feels cramped, even at full capacity. Our British menu works well for any gathering, from substantial wedding breakfasts to standing canapés during cocktail receptions. Air conditioning keeps everyone comfortable year-round, and our Wi-Fi actually delivers when you need to share those celebration photos instantly. Book the whole building and make this slice of London history yours for the night. Our team knows these rooms inside out and can help plan exactly how your party will use each space.
