Dining at Chinese Noodle Restaurant is perhaps a lot more civilised during off-peak hours (late afternoon or early morning) as crowds from all corners of the city tend to take over this small, packed restaurant, reducing your experience to basic necessities (read: shared tables) and rushed meals (they would "politely" ask you to pay the bill whilst you're still eating).
But don't let that cloud you from enjoying their beautifully handmade noodles and dumplings. Beyond the tacky dcor and unpretentious staffs with communication barrier, their food offering is perhaps the closest you can get to experiencing authentic Chinese noodles and dumplings as they were originally intended, albeit sans striking presentation.
Try not to compare the food from this shop with those of modern Chinese food establishments. The noodles are quite thick and filling, and so do the dumpling "skins" -- yet they are still delicious in its own right, taste and texture wise.
If you are pressed for time, then the soupy dumplings (xiao long bao) is probably one menu item to be avoided as this particular dishes takes longer to make (I have confirmed this both during peak and off-peak hours). But if you dont mind the slight wait, I highly recommend this dish: much-larger-than-usual dumplings that are probably one of their signature dishes that only delicate expertise can make.
