Event organisers who are looking for a party venue in the capital should consider Revolution bars, according to the company.
It said its London venues, Revolution Leadenhall and Revolution America Square, are the ideal places to party.
The popular bar chain, which is celebrating its 15th birthday this year, said it can cater for events, no matter what the size of the group is or the reason for celebrating.
"One of the most popular bars in London, Revolution Leadenhall sports some of the finest food and spirits to be had in the UK," it said, adding that the venue includes four levels of bars and restaurants.
This makes it ideal for all types of events, the company suggested, because it is possible to have a quiet meal right to a club night.
The new Revolution America Square is available to hire for private groups and also accepts reservations for breakfast, lunch or dinner.
Back in January, the chain launched its birthday celebrations with a new 15th Birthday Cocktail Menu.
