Went to Mark's for dim sum today. The Dim Sum in my mind is little above average. They raised the prices a while back, it is not that cheap anymore. And, you can find much better dim sum in MD.
However, there was one standout today. I had thin egg noodle soup with roast pig (they were out of HK dumplings). It was amazing. The soup was clearly made with some care. Really great flavor and feel. Excellent. I would highly recommend it.
