Yeah that's a hard pass on the shrimps, but thanks for the rest I believe I tried caldo de cana when I was in Brazil, but that's too long ago to really remember it. I do know I tried coconut water straight from a fresh-cut coconut and now, 9,5 years later, I'm still trying to get that taste out of my mouth.
I'll probably only have 1-2 full days in São Paulo though (and longer in São Carlos and Caraguatatuba, but especially in that second one I'm already promised several churrasco's ), so I'll have to make some choices (and it's not entirely up to me), but the pastel definitely sounds like a must-try. One with cheese, one with ground meat, one with chicken, one with ham and maybe one with shrimps so I can say "I'm getting fat, I'll just not eat the shrimps one".
