So tonight I'm about to cold approach a girl I've had a crush for some time I've noticed (not stalked) that she hangs out with her friends after dinner And that's where I come in and ask her out

So I'm going to say " hey you seem like a cool person, I was just wondering if you wanted to hang out sometime ?" (Her friends are going to be around I guess)

Is this good enough or is there anything else i can do ?
