The list of the 100 most influential people in the industry was topped by Jonathan Emmins, founder of agency Amplify. Last year's top-ranked professional - Michael Wyrley-Birch, chief operating officer of agency TRO, was placed third.
The party was held at Streetfeast London's Dinerama in Shoreditch, home to nine of London's street food traders and eight bars, including 50s-inspired cocktail bar Zephyr Lounge and an alpine ski lodge.
The evening kicked off with entertainment from London Contemporary Voices choir, before the rankings are unveiled, with a DJ helping guests to party late into the night. Guests feasted on a variety of dishes, including pulled pork buns, marguerita pizzas, chicken tacos and salted caramel doughnuts, with catering provided by Breddos Tacos, You Doughnut, Smokestak UK, Fundi Pizza, Farang London, Yum Bun, DucknRoll and BBQ Lab.
More than 9,000 votes - a record number - were cast for this year's Event Club. For the first time, the list included the top 30 professionals aged under 30.
Event will be releasing details of the full list online this week. Find out who is in the Event 100 Club 2017: The top 50 by clicking on the link.
