The coffee drinks aren't great (e.g. my cappuccino was a latte), but the atmosphere is so cool it's hard to be totally annoyed. If you go in simply for the black coffee, you'll be okay.
There's free WiFi, always nice, and a dozen comfy chairs where you can settle in for some reading and street-watching (as the chairs face the street).
The only really annoying part: the television in the back. On Sundays, I've had to endure football at the cafe. Not that I mind football (I'm sitting here watching it as I type), I simply don't go to cafes so I can watch that.
