Do something active that allows for conversation. Things like movies are trash for a first date. You can't talk, there's no way to get to know the other person.

Something like a park, or a light hike is ideal. You get to experience something together in a conversational atmosphere. Where I grew up there's a nice park by the river. It's well lit, safe, and relatively public; while still being a beautiful place to visit. It helps everyone involved feel safe and gives ample time to chat and see the sights.
