The 174-cover site is inspired by the army mess bars of India, and will offer pool, card games and live sport on-demand when it opens in May.
It is the latest project from the Sethi family's JKS Restaurants, which is behind London's Gymkhana, Trishna, and Hoppers.
Brigadiers will be split in to a several rooms with different functions. A reception area, complete with in-house shoe shine attendant, will act as a gateway to the Blighters restaurant and bar - housing a central bar and TV screens - and the more intimate Dining Room.
The Pool Room will feature a full-size pool table, as well as a whisky vending machine and self-serve beer taps.
There will also be several private dining spaces available to hire.
The menus will focus on barbecue cooking, with dishes including chaat masala pork scratchings, smoked roe and fennel raita; goat chapli and smoked bhuna goat bun kebab; and The Brigadiers Tandoori Chicken Club Sandwich.
There will also be a Mixed Grill menu with a selection of on the bone cuts, steak, ribs and chops; Chotto Chatpata (translated as fiery small plates); and feast menus for groups with dishes such as whole suckling lamb biryani.
Drinks will range from on-tap cocktails such as a Nitro Espresso Martini, to a monthly-changing beer list served in schooners and half pints.
Watch out for the JKS Restaurants team on the cover of the March issue of Restaurant magazine, out on 27 February.
