Kudos, which is one of the catering arms of the Crown Group, will be feeding more than 320 senior figures from the UK and Gibraltar.
Later this evening Seasoned Events, also part of the Crown Group, will host a reception for almost 1,000 people from the world of finance, politics, tourism and shipping at the Guildhall.
The event, in its tenth year, is the largest ever and has increased in popularity year on year, testament to the strengthening of ties between Gibraltar and the City of London.
Crown Group CEO Charles Beer said: "We are very proud to be able to host these two events for the Government of Gibraltar. We understand the significance of such events for the business world and are pleased that we are able to support this in such a capacity."
