I agree with Goucho about asking who the customers will be.
Every country has its own set of tastes, and Argentina makes meals the way they like them for the most part. I think Argentinos have a narrower palate than, say the US (again, my country of origin, so it's my comparison).
I thought at one time about opening a Cajun restaurant here (within my first year of living here). I make a mean gumbo, etoufee, etc. Even maybe throw in some Texas chili.
I have one or two Argentino friends who like it, but found it too spicy. Many wouldn't even try it, or tried a spoonful of gumbo and started flapping hands in front of mouth to cool down. So I tried to make it less spicy and it just didn't taste very good.
But there might be a market for something like NYC-style Pizza. I don't think it's too far off the main tastes here, although it would be different. They might not like the way it tastes and feels next to what they are used to.
