Dozen is now under new ownership! After closing last year, they've reopened under, I believe, a passionate former employee's ownership.
My boyfriend and I ventured to their Lawrenceville location this Sunday, which also serves brunch (we usually stop by their Oakland location). Their food is of good quality, creative, and in generous portions. We almost didn't have room for a cupcake (Root Beer Float, one of the rotating specialty cupcakes). The table service was attentive, but not overbearing, and the employees were friendly and helpful.
We will definitely be returning for brunch again on Sunday mornings. For us, Dozen is a Pittsburgh institution!
