Best Places to Source and Develop B&W and Colour Film?

Where are you based?

Dredge alert!

I wanted to tap up the photography community, is there a good place where I can get above average digital developing done in London? It doesn't have to be uber professional but above Snappy Snaps would be nice.

I'm new to digital photography (just got a Pana GX1) so am pretty clueless as to the best way to develop the pics...
