I'm going to give this 4 stars because there are very few options for Malaysian and Dim Sum in Pittsburgh but if this were in a larger city it would probably be more like 3 stars.
I went there once for lunch and had one of their Malaysian noodle soup dishes which was pretty good but not amazing. I also went for Dim Sum on a Sunday and very much enjoyed it. They had a large diversity of options and everything was very tasty. It's certainly not at the level I've had in places like Boston, Seattle, or NYC but for Pittsburgh I was very satisfied. My friend who had lived in China for a year also found it to be pretty decent. I would definitely go there again.
The service was very good and the prices reasonable. The atmosphere was comfortable though I found the lighting to be rather dark. There is also some outdoor seating available when the weather is good and a full bar with seating.
