It's fine, except for a minor grammatical error: She likes to try new things (or, she likes trying new things)

You could say that, but another way to answer would be to say "She is open minded".

What's she like? = What IS she like? The answer would have to describe the personality/character of the person, not something that the person likes to do. This is not the same as "What DOES she like? I hope this helps :)

question: what does she like? answer: she likes to + infinitive or she likes verb+ ing to like has 2 options , both are correct

I've corrected it. But it is better if you understand it first to improve faster. This is basic.
