Anywhere you can talk a lot really. As someone else said don't go to see a movie, that's more of a second or third date kinda thing (at least the way I see it)
The main issue is awkward silences, just try to think of things to ask when that happens in advance because you can never quite seem to think of anything at the time. People find it easy to talk about themselves when asked. Try not to ask questions you can't answer yourself (for whatever reason) as they will almost certainly ask you the same thing.
Now, I never even considered awkward silences happening on my first date (at a cafe when I was 12) and they did happen but it never ruined it, it actually went well. It was her first date as well although she was a year older. Keep in mind the other person is probably just as nervous.
And a kiss is enough at the end, don't even try anything more than that. Even if you are of age.
