I don't know why I never thought of it before, but surely Yum Char must be the best choice for eating out with a half-Chinese finger-food fanatic?
The only thing I can think of as a possible problem would be if The Little Madam reacts to the prawns or soy sauce, of which the latter is of course a mainstay of Cantonese cooking. Oh, and MSG of course. And having to check for egg. Well, no cuisine is perfect.
But really, little bits of meat and veges wrapped up in little bitty parcels? We already know that TLM likes deep-fried wontons; I'd be shocked (and stunned) if she didn't take to at least one or two of the many dishes which are paraded around the tables. Though perhaps not the chickens feet.
On the home-cooking front, I've just tried her out on asparagus rolls. She didn't take to them (so, more for me), but on the other hand she did like the avocado open sandwich I was eating.
