Noodle Asia is a staple to all my vegas visits. I've been coming here for over 7 years and the food is always fast and good quality. Unfortunately the prices have also climbed up pretty high every time I visit as well. They usually seat pretty fast, try not to come at the super peak times and you'll be alright.
I will usually get some noodle soup and it's well made. I also love their open kitchen layout which you seldom see in Chinese restaurants. You can see who is working on your food and their entire workspace! I guess that helps hurry them up to make food quicker but the quality certainly doesn't lack. Expect to pay around $20 per person at minimum when you come here.
