They are also in the freezer section of Lotus Foods (next to whooleys in the strip district) and Many More Asian (also strip district). I would not buy the dried noodles as they just are not the same.

If you're feeling really ambitious, you can get the ingredients and make them yourself. This is a 2 day process, but so worth it when you get it right!! Get the cake flour from the asian food markets if you want to go that route.
