If not for the indie coffee passport I would have never made it down to Differance, but I'm glad I did! Friendly staff, nice atmosphere, and tasty coffee, what more to ask for?
They're brewing 49th parallel and Phil & Sebastian, all good there.
The only downsides - while the place was mostly quiet, rocking out to good music, huge crowds would just pop up from time to time. Also, not much seating, and you essentially sit in front of a big mirror. Best not have anything sensitive or incriminating on your laptop...
