This question is similar but doesn't address this question of comparing different ways to express the notion of preferring A to B.
Are all these ways valid grammar for asking if someone prefers A to B? (In this case A is Chinese food while B is American food.)
Expression #2 seems like it might be wrong.
- 妳喜歡中國菜多過美國才嗎?
- 中國菜比美國菜妳喜歡多嗎?
- 妳覺得中國菜比美國菜好吃嗎?
