I had to radically expand my palate when I traveled for a month in the Middle East. The food just showed up at every place we ate and it would have been beyond rude not to eat it. So eat it I did. I could still eat hummus at every meal. Goat was better than I would have expected. 
I will try about anything once (except bugs). 
Tried veal once, and it was okay, but the thought of the poor baby cow kept getting in the way. (That would be my problem with Roo too).
