Concerts
Concerts are places where everyone enjoys themselves. The music, cheering of the crowd and the vibrant lights can be very exciting and fun. Concerts may not be the best place to talk and bond, but having fun together definitely the best way to create beautiful memories with each other. It can bring you two closer by breaking the walls of formality and unwanted decency.
People tend to be more of themselves when they are having fun or is happy. Thus this would be a way to see the fun, never-seen-before side of your friend.
