Last week, I attended a group dinner at Jardin de Jade (Jade Garden) on Maoming Lu, which I believe is a chain restaurant. The dinner itself was a 3 hour affair, consisting of many small dishes that I didn't care much for. However, they finished things off with 小龙包, which was really good. Perhaps I was biased because I was so hungry, but I felt the quality was top notch.
Most of my hole in the wall XLB venues no longer exist, so I really only get to try DTF and a pretty bad hole in the wall near Laoximen these days. I'm not a fan of Yang's because I haven't figured out how to eat those things without making a mess.
