When I was a child, I was the pickiest eater EVAR. I grew out of it and am now a pretty adventurous eater.
Indian food never looked "gross" to me, with two exceptions: dhal and paneer. I tried masoor dhal (the red one) and nom nom nom

But most dhal is on my shit list, as is paneer.
Eel sushi initially looked disgusting to me, but I went out for sushi with a few friends, and we ordered an eel roll, and I was convinced to try a piece - nom nom nom. I have a limited tolerance, though - I'll eat one piece of eel sushi or I'll split a roll with someone, but I prefer other types of sushi.
