Gherkin Skyline Bar: Sunday Jazz Concert

If you've only seen the exterior of the The Gherkin, this is the perfect opportunity to explore its innards. The proceedings kick off with a presentation introducing the building before guests are whisked up 40 storeys to the exclusive lounge bar to sip mojitos, admire the fantastic views of London and listen to a 45-minute jazz concert performed by the 'Blue Mojitos'. Tickets must be booked in advance.
