Honestly as a Chinese, Noodle here is just good, nothing special. However, here is not China, I don't have so many choices.
I have lunch here very often since the noodle here is better than that in other Chinese restaurants. I recommend the #2, that is my favorite one, noodle with pork sauce. That one is delicious that I can't find anything to substitute it.
They made the noodle in front of their costumers. Many Lanzhou-noodle restaurants doing it in China so I feel it is very common. However here is a non-Chinese guy makes noodle here, which makes me feel very interesting:)).
I recommend here totally.
