It turns out there is a Chinese restaurant that serves Dim Sum on the scale of what you find in San Francisco or New York. Of course it's in Richardson and occupies a large space near Central Freeway and the DART red line. I am not sure there is a DART stop near the restaurant, however.
If you go and don't know what dim sum is, it's basically small food portions served in small metal trays. There's a lot of shrimp and pork, a rice soup called congee. My personal favorite is the fried taro ball. Sunday is the most popular day to go, but the prices are reduced on weekdays.
