OT best free wifi in Cambridge Re: Q: Why does my firewall hate the cambridge picturehouse?

[Ferg]

The Picturehouse bar has free and fast wifi without any encryption* or

cannot be a finer place to go spend some quality mobile computing time  
there!

Cheers

*something to bear in mind if you plan to check your bank account.   
Although I guess any public wifi spot is a potential danger.
