The new South End location is great! Lots of seating, including a separated room that you can use, or reserve for meetings and the like. The location is great, right on the corner of Camden and Kingston. The ambiance feels different; the other location is more hipster, this is more generic, but cozy. That may change as they add more artwork and things to the store, but it's not a downfall at all.
Today is opening day and the place is hopping! I stopped by for a vanilla latte (mmm!) around 10am and it was buzzing. Friendly service, great coffee, delicious baked goods, you can't go wrong!
