Spokesman Eddie Gershon said: “We have always been against the late night levy as we believe it to be an unfair tax on pubs.
“If the late night levy is introduced then we will review our closing times at our pubs in the borough.”
Andrew Beaumont, landlord of The Bucks Head pub in Camden High Street, added: “This will be a burden on the smaller pubs in the borough.”
According to council documents, 271 premises in Camden are liable to pay the levy, which could bring in a maximum gross revenue of £360,240.
Proceeds will be spent on street cleaning services.
Councillor Jonathan Simpson, Camden's cabinet member for community safety, said the council's decision was taken after "careful consideration".
He said: “The funds raised by the modest levy will go towards providing additional services, including street cleaning and pop-up urinals, to help ensure residents and visitors to Camden are not negatively impacted by the night time economy.
“The decision to implement this levy has not being taken lightly and comes as a result of significant consultation which residents and businesses, the majority of whom were in favour. Once implemented we will monitor the progress of the levy very closely and conduct a review after 12 months.”
