We tried the Lan Zhou noodle and the Fish Noodle w/ Pickled Veg last night, and I highly recommend trying the fish noodle. The broth was absolutely amazing- perfect combination of hot and sour and had huge slices of fish.
We chose two types of noodles and I'm a bigger fan of the knife cut noodles (thick and chewy!) than the flat wide hand pulled noodles (got soggy after a few min in the broth).
Also recommend trying the sliced pork with garlic sauce- tender pork and lots of minced garlic. Just wish it was spicier! The house special pancakes were just oversized gyoza. Nothing too special. The beef filling was flavorful and juicy though.
Food came out really slow, so it was nice to be able to watch the noodle making from the dining area. Service was ok. Good location in the SW, fair prices, good portions- 4 stars
