I used to go to the Canterbury one a lot in my teens.
These days I stick to Ashford or Folkestone.
Ashford has the multiplex - but sadly it's out of the town centre! It's okay - I've been there to see "The Departed".
Folkestone has that "Silver Screen" cinema. I've never been. It does look quite nice. A nice cosy feel to it - from the pictures on the web. I think I have walked past its entrance on the high street in Folkestone. It does have a balcony as well. Adds to the novelty I suppose.
