Since you asked him out, it's up to you to decide where to go or what to do. Simply call him up and say hey, if you're free Friday night I know this little sushi place (or some other place YOU might like), why don't you pick me up or we can meet there, and take a nice walk after and maybe get some coffee.
Just keep it simple and fun. Remember you like this guy, and you want to let him know that but don't give up anything other than maybe holding hands or a light kiss until much later down the road. Trust me, he will respect that if he is looking for a relationship. If he tries to get down and dirty within the first 3 days, he's only looking for a hookup. Good luck!

If you're old enough, go for some drinks! Something that allows you to relax, be able to keep eye contact, maybe a little touch here or there etc... 1st date stuff
Or you could go to a museum- I love that, it's so fun and if the convo gets a little dry (which is normal) you can chat away about what's around you! Well done on asking him out by the way, thats pretty F* brave!! You go gal!
