Steinbeck & Shaw will close for the summer as it undergoes a refurbishment and rebrand.
New owners Club Chemistry started trading on Tuesday and will give the venue a makeover and new name.
But owner Louise Jones-Roberts, a Conservative city councillor for Barton ward, is not revealing what that will be.
In February, the Canterbury Journal reported that Club Chem was moving forward with buying the St George’s Place venue, which has previously been Chill and Churchill’s.
She said this week: “Our first trading session went very well, but we will completely refurbishing this summer.
“It will be completely different inside. In terms of what we do, we’ll still have the midweek nights, but you will also find an older clientele who will feel more than at home inside.”
Louise says she expects the closure to start in July and to last four to six weeks.
It should reopen in time for the new academic year when thousands of students pour into Canterbury to start their university educations.
With two prominent nightspots in the city, the company will dominate the late night market in Canterbury.
Club Chemistry at Station Road East has been a popular nightclub for years.
Louise has said her company is also working on being environmentally friendly. “We are looking to install kinetic dancefloors which convert dancers’ energy into electricity, and we have just become one of the first to ban single-use plastic straws and cups,” she said.
The purchase of Steinbeck & Shaw is understood to have come in at £1.5 million.
Although Canterbury has earned itself a reputation as something of a party city, there are concerns about late night noise caused by revellers.
