Glendola Leisure Group is to open a new bar and restaurant called Silk & Grain, specialising in steaks and "aged" cocktails.
The 163 sq m, two-floor venue in 33 Cornhill in London was previously called the Door.
The first-floor restaurant, seating 56, will offer a selection of different dry-aged steak cuts, cooked in a Josper grill, alongside British-inspired mains such as lemon sole with garlic and caper butter; and Suffolk cider soaked, slow roasted pork belly.
A range of classic cocktails has been given new depth by ageing spirits in different materials including oak barrels, metal, leather and glass, with the aim of adding complexity and flavour to the drinks.
Starters will cost from £6, mains will range from £12 to £20 and desserts will start at £5.
Alexander Salussolia, managing director of Glendola Leisure, said: "We're incredibly excited to be launching a premium City venue. It's a key site for us and we think that our unique aged cocktails will excite both the consumer and industry."
