I really enjoy their noodle and it is definitely a hidden gem tucked away in the dark corner of a foodcourt. TBH, if I haven't had awesome noodles at their restaurant location, I would have never noticed them in the first place.
I usually go for the potato noodle, it is very chewy (in a good way) and offers a unique texture that is uncommon for Chinese soup noodles. I've tried their pork ribs and beef toppings, both are melt in your mouth tender. The soup is also extremely fragrant and flavourful, so good you almost want to drink the whole thing.
All in all, great food. Not entirely sure about the sanitation but doesn't stand out as dirtier than any other Chinese food court stall.
