Police were called to the kosher Tish Bar & Restaurant in Belsize Park on Thursday evening last week after a member of the public reported a “large gathering” at a function there.
Although the caller mentioned around 100 people, the Metropolitan Police said it could not verify numbers.
“Officers attended as the group were leaving the venue. No arrests were made and advice was given to the organiser and owner,” the police stated.
According to government guidelines, a maximum of 30 people are allowed at wedding ceremonies and celebrations.
