The City of London is filled with secrets. Doors open out into all sorts of unexpected gems. Threadneedles is one of these. An unassuming door is marked only as the hotel’s entrance by a porter – I know that I’ve actually walked past it several times and not realised it’s there. Inside it’s like Aladdin’s cave. Originally a Midland bank, its circular ‘lobby’ is dominated by a stunning domed stained glass ceiling. With natural light flooding into the space, it can be used for small meetings in its comfy chairs and striking red sofas but it’s also a perfect area for a reception of up to around 150. As the hotel lobby it can’t be totally private, however this shouldn’t put off potential parties, as it has real ‘wow’ factor. Circular pillars support the dome, while a custom made blue carpet has an orange and red crayfish on it to draw the eye, and the walls don a display of Laurent Perrier bottles – a nod to the hotel’s partnership with the Grande Marque.

There is no room hire but a minimum spend of £6,800 or the or area can be reserved for a minimum spend of £ 42.00 per head on food and beverage. Marco Pierre White Wheeler’s of St. James’s Oyster Bar and Grill Room is the hotel’s restaurant, although many may not have realised they are connected. Equally striking, its central island sees banquette seating forming the layout of the room, while huge windows with ornate ironwork are framed by dark blinds. There’s a large walnut screen at one side, central white pillars and a glass light box screening the service area. It’s a fascinating mix of the classical bank and modern design. It’s sumptuous yet simple and available for breakfasts, lunch and dinners – ideal for weddings or corporate dinners alike (80 seated, 200 standing with the bar). The hotel also offers three other smaller private rooms: The Traders Room – a small meeting room with a single round table for up to eight guests. Used mainly for meetings and interviews, it’s also an ideal space for a discrete or intimate dinner.

Next door, the Capital Room (20 seated/35 theatre) and Sterling Room (10 seated) interconnect. They are both simple and elegant. Understated and modern, without the grandeur of the high ceilings in the rest of the lobby, these are well suited to drinks receptions followed by a dinner or lunch, although they are also kitted out with AV behind dark wood panels for meetings. The masculinity of the mushroom walls, dark wood and mid back chairs with brown arms are given warmth by the cobweb design opaque central overhead light, which can change colours from warm cream to green and blue hues.
