Even though a nice ride is great you can't get to know someone that way. Someplace quite for a drink or coffee if you prefer. Eyes, I believe are the windows to the soul, so may I look inside?
Go for a ride, stop at a few places for a beer or two, talk get to know each other then maybe fund a great little place for dinner or lunch by the water.
I think drinks and a few games of pool is good because you can talk and get to know one another. Also a bike ride would be fun. Just depends on the other persons likes or dislikes.
maybe just meet for a drink at the corner bar or a cup of coffee at a cozy restaurant..? get a feel for one another. if having a good time, find a good supper club and enjoy some steak or seafood.
