I ordered Biang Biang Noodles. Mid China authentic dishes. The noodle itself is cold but the sauce is warm. They also have a hot plate option, it's the oily Biang Biang noodles, I'm guessing they will pour the heated oil to the noodles? Anyway, worth it a try. Tomato+egg+beef is the main ingredient. A little bit Italian style? LoL
