Honestly, my son wouldn't touch most of the items on that menu. My husband and I both enjoy different cuisines from different countries. I cook all sorts cuisines at home as well. When my son was a toddler, we lived in walking distance of quite a few ethnic restaurants. To fend off cabin fever, I would bundle him up and put him in his stroller and go to one of the restaurants for lunch and he would eat off my plate. He loved Thai and Indian food, especially. Then, I had to put him in day care and that was the beginning of the end. He stopped eating the korma I would share with him and wanted mac 'n' cheese or chicken nuggets--all the things he was eating in day care. He loved all sorts of fruit and loves milk/cheese, so I did feel less guilty about letting him have those things. He was always in the top percentile for height and a little below average for weight.
I did cook separately for him, only because the things he wanted were so simple and I could make healthier versions. I also don't know too many American four year olds who would eat vindaloo. But he is 14 now and cooks for himself. I tell him what we're having for dinner and he decides if he's going to eat what I am cooking or if he's fending for himself. It is simple things like shrimp stir fries, but he's getting there.
As far as palates go, he and I are opposites, sometimes I can't believe he's mine
