...Tainan or Hakka sizes that Costco carries. Noodles are really good; sauce is pretty basic. You can get the Mandarin size at either an Asian market or Harmons (Harmons also carries the hard-to-find A-sha knife cut noodles...haven't tried them yet though).

Some other good ones you may want to try are:
Nissin Raoh Miso (Walmart, Smiths);
Indomie Mi Goreng (Walmart, Smiths...the satay flavor was the best, but you can't find it anywhere anymore);
Tseng Noodles Scallion With Sichuan Pepper Flavor (asian markets);
Mom’s Dry Noodle Dan Dan Noodle (asian markets);
MyKuali Penang White Curry Noodle (asian markets);
Kiki Noodles Scallion Oil & Soy Sauce (asian markets);
Chukazanmai soybean paste flavor (Walmart).

If you have some spare time, you might want to check out this site for ideas. This guy might like ramen almost as much as you.


Also The Way of Ramen youtube channel is fun. He mostly does serious ramen stuff, but sometimes does ramen pack hacks. I tried this one the other day, and it was shockingly good.
