Well, after living here for 2+ years, I have finally found a Chinese restaurant that serves cold sesame noodles. Given that this dish is particularly delicious in the summer, the timing was perfect.
Despite the reviews posted separately, the dish was hidden on the list of noodle dishes (vs. appetizers) at MuMu on Atwells.
The noodles are not as sticky as I am used to, and don't quite compare to their counterparts served in the NY area. But they were certainly tasty and close enough to what I have been looking for all of this time. Just wanted to share the news!
