The Enterprise lease, which is run by licensees Susie Clarke and Joel Czopor, was selected from the Great British Pub Award’s 17 national category winners to take the top title.
Clarke and Czopor were presented with their award by Sky Sport’s F1 presenter Natalie Pinkham at a glittering sports-themed awards ceremony at the Hilton Hotel on Park Lane, London. The awards are organised by the Publican’s Morning Advertiser.
The pair were also named national champions in the Best Partnership Pub category.
Judges were impressed with how the Grafton is a diverse modern business, that remains true to the ideals of a traditional pub.
The Grafton offers a fantastic range of events and promotions, which helps stimulate business across all days and day parts. In the past year an impressive new all-weather roof terrace has opened which has seen sales increase by 40%.
The pub won Best Entertainment Pub in last year's awards and among regular events are Wiff Waff Wednesdays, open mic nights, quiz nights, clothing swaps and sing along Sundays.
A great drinks offer is in place with eight hand pumps rotating award-winning ales, local craft beers on tap and in bottles and wines and prosecco on tap.
Publican’s Morning Advertiser editor Rob Willock said: "The licensees of this proper cornerstone pub that sits in the heart of Kentish Town and Camden’s community leave no stone unturned in their quest for business building ideas and GP improvement.
"The product range, the service standards and the use of under utilised pub space has opened up new possibilities for this pub that have transformed its prospects."
National champions were also announced at the ceremony in 17 categories, selected from 90 regional winners.
