This could be as good as it gets at Jing. In the past, Charlie Huang's restaurants have seemed to suffer from the grinding repetition. Right now, the kitchen is still new and amped up over its woks and French knives. The cooks are still excited by lo mein and, when they have the time, will make the best lo mein you've ever had. So go now while the place is still great, before it becomes jaded and buried beneath its own inevitable success, before time, trade and diminished expectations take their inexorable toll.
