"We have had a bench stolen and more damage caused on other occasions but didn't pursue it.
"There was a lot of mess this time and we couldn't keep quiet.
"Someone has to recognise these people."
Once a few of the men had finished using the restaurant frontage as a toilet, three of them then rip out flower displays, throwing pots across the pavement.
The video then shows one of the men kicking over a dustbin before they all walk away.
Police spokesman Martin Very said: "We are investigating an incident at a restaurant in Chatham Street, Ramsgate, at midnight on Saturday, June 18.
"It is reported that a group of men caused damage at the address."
