Conozco a un grupo de personas… (Relative Pronouns)

Es la gente a que conozco?

La gente a la que conozco?

I hope this demonstrates what I'm referring to – with relative pronouns I always struggle to know whether or not to include the definite article (el, la, los, las). I saw this example of a correct sentence online;

"¿Has ido al café del que hablaba?"

Why can't we say "¿Has ido al café de que hablaba?" Thank you pals!
