Omar Wilson, 31, repeatedly punched and kicked Mussie Imnetu during an altercation outside the Dr Power restaurant in Queensway, west London, on August 26 last year.
Mr Imnetu, who worked at The Arts Club, a private member’s establishment, was taken to hospital and died four days later without regaining consciousness, jurors heard.
About a minute later, Wilson punched Mr Imnetu five times in the head, causing him to fall to the ground.
Wilson continued to punch Mr Imnetu repeatedly while he was on his hands and knees, then kicked him in the head.
Mr Imnetu’s wife, Linda, described her husband as “respected, admired and loved” in a pre-recorded victim impact statement played in court.
