The survey of 20 companies with 1180 sites revealed that 20% of operators experienced like-for-like sales increases of 11% or more on last year, underpinned by a further 30% reporting like-for-like gains of 6 to 10%.
The survey confirmed that just 10% of operators reported delivery difficulties as a result of the Games.
ALMR chief executive Nick Bish said: “The public perception was that London wouldn’t be able to handle the Games influx, so people stayed away. But these fears were unjustified and then it became clear that pubs and bars were after all the best place to celebrate the success of Team GB.
“It’s heartening to see such a turnaround after a difficult first week of trading and to report that pubs and bars are an essential part this is a testament to the warmth, vibrancy and vitality of the modern British pub.
“The significant improvement in week two indicates both the massive outpouring of support for the London Olympics and the wonderful work done by entrepreneurial operators to ensure that everyone who came out to experience the Games was able to enjoy the very best of British hospitality.”
