Might try any of the Sichuan places....they have a spicy cold noodle
Royal Sichuan in Richardson

I would also call Hong Kong Royal in Carrollton as they might be receptive to preparing the dish for you.

I know of two places serving "Dan Dan Noodles" (cold szechuan noodles) in Dallas not previously mentioned above.
1. Tongs House. The very first restaurant in Dallas to serve this cold noodle dish. Over 40 years ago!
2. Mr. Wok Asian Bistro
Confucius say, "long black hair in noodle good sign for long life" Confucius also say, "but, long black hair in noodle, disgusting".
To the best of my knowledge, NYC sesame noodles are really a NYC thing. Central Market makes a version that they sell in their deli case. I have never had sesame noodles outside NYC. CM's doesn't use the same noodles. If it were me, I'd go to Super H-Mart and buy the noodles and make it myself. You can download a recipe off the internet. I've seen the recipes. It's so easy and you can add more veggies. Don't do Uncle Tom's or Annie Chun. You're in Dallas and have access to decent noodles.
I've had many Chinese noodle dishes where they use sesame paste and they are similar to NYC sesame noodles, but the NYC version is definitely Americanized. Don't most versions have some peanut butter? In my experience, the noodles using sesame paste tend to show up more at Northern restaurants than Cantonese or HK style places. Try Little Szecheun. They won't have the exact same thing, but the more authentic version is absolutely delicious.
I just ran across your long-ago post about szechuan dan dan noodles in Dallas. I love this dish and my favorite place to eat it in Dallas is at Szechwan Pavillon, Buckner @ Garland Rd, Dallas. They call it Noodles with Hot Sesame Sauce on their menu and I'm not sure how authentic it is because it is very garlicky. They serve it with an awesome kind of Scechuan cole slaw that is not even listed on the menu. You can download their menu from their website (remember they spell it Szechwan). Of course, this restaurant serves many other wonderful dishes but as far as I'm concerned, Szechwan Pavillon's version of Dan Dan noodles is the ultimate comfort food and the worth every penny of the $3.50 price- I'd love to have the recipe.
The newly opened Noodle House in Plano, Coit and Park inside the former May Hua Supermarket space fronting Park and closer to the Walgreens has this dish. No idea on the taste just saw it on the menu.
