"Chang" refers to Chef David Chang, who is making some of the best, and most innovative, ramen outside of Japan.
He is the real McCoy, too, just a post modern, 21st century, Korean American world citizen who cooks with the best of them.
and his approach- opening a restaurant that serves really really good ramen, to a nation (the USA) that thinks Ramen is something that you buy ten for a dollar, is nothing to sneer at- you could learn a lot from Chang.
I recommend watching the show, "Mind of a Chef"- it was on PBS, but you can watch it in North America on Netflix streaming, it is a very interesting way to think about noveau japanese inspired cuisine outside of Japan.

Frankly, I think that tonkatsu and tempura would be successful- they are like Milanesa, only better, which all argentines eat.
Also, yakitori variations, shabu shabu, and similar beef dishes would be great here.
Some things, for sure, you could get from Chile. And Peru- lots of amazing japanese chefs and restaurants in Lima.
and, I suppose, if you went noveau, which basically means whatever you want it to mean, you could avoid air shipments from Tokyo, but, really- a lot of stuff is ONLY available in Tokyo- the good stuff gets pulled directly off of the boat, off south africa, mexico, or alaska, and flown directly to Tsukji.
I know fishermen in Alaska who deal directly with buyers from Tsukji, and the best 50% of their catch is in Tokyo by morning. Money talks, and where fish is concerned, the money is in Tokyo.
THEN, it goes back to the markets in Seattle or LA or NYC.
As I said, many of the best restaurants just cut out the middleman, and get direct fed ex coolers from Tsukji.
Tsukji, the physical building, may be closed right now, but the marketplace and auctions are surely going on somewhere in the Tokyo area.
I have been there, I love the little three wheel tugmotors they use for moving pallets of fish around.
and no, there is nothing vaguely like that in Buenos Aires. Frankly, there is nowhere like it on earth- but there is REALLY no fish market like that in Argentina.
