Question: what do you say when someone says que tal?
Answer: 2 Answers. Bien, bien,¿ y usted/tu? Muy bien, gracias, is the straightforward reply and as Annie says it is polite to ask how they are. You could also say 'genial' or if your feeling out of sorts 'asi, asi' [so, so] The last two answers are to someone who is interested in how you feel ie a friend.
