I love Commonplace. Their coffee is fabulous, and it's a great (and convenient) place to do some work on a rainy day.
My only complaint is that their music is - consistently - well, weird. Today I'm listening to some odd wailing electronic music that sounds like it belongs in a haunted house; the other day it was intensely loud. Other days it's a more pleasant mix of singer/songwriter, jazz, or old-school country, which is more accessible to a wider audience -- but I always plan on bringing headphones to drown out the weirder (and more unpleasant) days.
Despite this, their coffee and lattes are great - and completely worth the noise on those off-days. Just bring yerself some headphones.
