The first time I went to Mexico, I was excited to get a fresh coconut, a hole cut in the top with a machete and a straw inserted. It was much less refreshing than I expected, so I don't understand this trend.
I've been back in the states since June. The coconut juice/drinks sold in the stores taste nothing like actual coconut juice. I'm not sure people would go as crazy over the real thing...but who knows.
