I've been waiting for Yum Bunz to open---the "coming soon" sign has tempted me for months. So I was happy to give the place a try. The interior has great graphics---is that a must in restaurant design these days? The staff was helpful and the service efficient.
My bun was filled with chicken. Although it was perfectly OK, this was the part of the meal that I found least inspiring. The filling had a little too much sauce for my taste; it was advertised as spicy but I didn't find it to be noticeably hot. The dumplings were extremely fresh off the pan. The filling was fine but not exciting.
Overall, I would rate this as a good local lunch stop but not a substitute for the Chamblee dim sum scene.
