Vincent also spoke about the impact of tax rises, which he said were "incredibly toxic" for the hospitality industry.
He said the upcoming rises in business rates along with overall cost increases meant the High Street was no longer as profitable. Leon has been losing £10m a year.
If taxes on businesses increase further, he said, "the only people that are going to survive are those selling... food that's not very good quality".
In April, business rates relief for the hospitality sector which came in during Covid will end. At the same time, increases in the rateable value of premises take effect.
The Treasury has indicated it will announce further assistance for pubs in the coming days but has faced a backlash from other hospitality businesses over why they are not included.
Chancellor Rachel Reeves told a press conference on Wednesday she was "working with the hospitality sector".
