I'm not sure is i say it in the right way,is it Que comida preferido? I have absolutely no clue... well that's why I am asking? Please answer my question!
What is your favourite food?
Hi Pika. Welcome to the forum.
¿Cúal es tu comida favorita (preferida)?
You're on the right path, "¿que comida prefiero?" is what food to I prefer/like. If you want to say what food do you like you should say "¿que comida prefieres?". You could also say "¿cual es su comida favorita?"
