Eating requirements: 食物要求
But I came across another term which I can't seem to find. A waitress in China asked me if I had any eating requirements/allergies but she used a term that I think had 口 in it. I think it was 2 characters with 口 being either the first or second.
你有什么 口X 吗？
你有什么 X口 吗？
Have I misremembered or does such a term exist ?
