Posted in the a different thread with no responses after a couple of day. This may be a more appropriate thread:

Anyone have a good recipe for dan dan noodles in the style they're served at the Cathay Noodle Bar? I have no idea if those are traditional dan dan noodles or if they are modified somewhat for the western palate given the mix of travelers on Cathay, but in either case I love those noodles and have been trying to find a recipe to use in an attempt to recreate them at home since I won't be enjoying them at an airport any time soon.

This food and wine article has a picture and talks about them in some detail for anyone unfamiliar:
