Rusty Nail is expected to open in the second week of May, with capacity for 80 people, a changing line-up of DJs, cocktails and premium whiskys. It will be open from 10.30pm to 3am, on Tuesdays, and from Thursday to Sunday. Monday and Wednesday's it will be open for private hire.
Aiming to feel like "a club within a club", the site has been refurbished to feel like the whisky cellars of a medieval-style castle, with décor that mixes the old and new - such as neon lights with old whisky barrels, stained glass windows and candlelit alcoves. House has confirmed that the cost of the club was £600,000.
Drinks will include flavoured whisky, and cocktails such as the bar's namesake Rusty Nail â' made with whisky and Drambuie â' plus Mystic Aroma, with Ciroc red berry, rocket salad, lemon juice, pepper, ginger, lemongrass, pink grapefruit and sirop de gomme; and Melon Bees, made with watermelon, root ginger, honey bees syrup, Johnny Walker and Martini Rosso.
DJ sets will play a blend of electro, disco and 80s funk and rock, and there will also be live dancers and regular live shows.
It will be the sister club to nearby Mayfair club, Whisky Mist. Both clubs are part of the Brompton Brands group, spearheaded by shareholders Piers Adam and Nick House.
The group's other sites include Mahiki and Bodo's Schloss, while House is also involved in projects including the recently-opened restaurant Steam and Rye.
