In the 1980s this was a branch of Fancy Free. Next it became Blue Velvet before being taken over by Greenhouse in the late noughties. They called it Greenhouse Lounge or Greenhouse United. In 2021 it has been rebranded as Cookies.
The earliest picture I have is inside Blue Velvet sent to me by Epsilon in 2005.
For a short time they had a restaurant next door called Munchies visible in the 2018 photo below.
