I think Cardiff's a fab city - lots of lovely shops and restaurants. I work just away from the centre so don't get to see it that often.
I love Dr Who as well, when they film in places I know I get sooo excited!! Also my next door neighbour played the Dr's double in the last series so that's pretty cool...
Omg, that's amazing! Last time I was there, I knew where they were fliming, but we just didn't have the time to get over there. It was only Donna and Wilf but would have been fun to see!
Unfortunately closest I've seen them filming is them wheeling a Dalek through Waterstones to a wrecked xmas market outside (for the xmas special a couple of years ago) but I loved my neighbour being in it - got all the spoilers this series and goss on the cast!!
