Real cheddar cheese is readily available at specialty cheese shops such "al quso queso" which are all over Barrio Norte. I've even found it at Disco and it is definitely NOT processed. Supermarket cheese is generally poor - tends to be the Dutch style that has a long shelf life. However some fine cheeses are made in Tandil, a prosperous farming town in the province of BA. They can be found here. Try the cheese shop at Patio Bullrich, for example. As for produce here, I find it quite inferior to what can be found in farmers markets, specialty shops or good super markets in the US. Lettuce is a prime example. There are fewer varieties here and it is generally quitre "picked over" and wilted. About taste in food, Argentines just don't care for spicy food. I think it has something to do with the confirmist attitudes that abound here. People just go with the flow and are disinclined to experiment.
