I had never stopped in when this was Alterra, so I was shocked to discover how huge this place is on the inside. Even with all of the seating it never feels like you are right on top of the other patrons, unlike most of the other coffee shops downtown. Lots of power outlets as well if you need to get work done.
I've only visited a few times, but so far the coffee and espresso drinks have all been pretty good and the staff are friendly. Bonus points for having a couple of beer options on a warm autumn afternoon. I suppose your opinion of the music will depend on your age...but I've been happy with the selection.
