You'll have to visit an Asian supermarket to find fresh or refrigerated noodles. I've visited several markets and the selections are always different. Look for big bags of thin rice noodles (pho) in the fridge and the flat wide ones should be nearby. The fresh noodles are usually not refrigerated and are on wire shelves near the front. You could also buy dried noodles online - A Taste of Thai or Three Ladies brands are available on Amazon.
