I burned many a good friendship this way, at least initially. If we're both mature about it, we become friends again (and randomly hook up from time to time, if our current partner is cool with it, which most are.)
I'm not sure which option you're referring to when you say "this way".
In my experience, if you go on a couple dates and it doesn't really click, it's easy to stay friends. If you just shut it down from the outset, it's a lot harder because it leaves unresolved tension (at least on the other party's side).
I didn't "like" mushrooms either, until I actually tried them. Now I'm hooked.
(The food, not the drug, just so we're clear...)
