I think US beef and Argentine beef do not compare, it's a bit like apples and pears. I like both, actually. However, there are some Argie cuts of beef that I think have nicer texture and flavor.
Do you remember which one? We tried Mr Ho, the Korean takeout place in Barrio Chino. The owner grew up in CABA, speaks perfect porteño and the bibimbap, bulgogi, and tteokbokki he makes are awful.
I like to cook and know how to make several of the most popular Chinese and Korean dishes in the States. Unfortunately, bringing all my kitchen paraphernalia was out of the question. I will replace that stuff, eventually, but I don't know how I feel about using Chinese made bottled sauces. In the States I used to buy only those made in the USA.
