One off chance encounters like that on a bar or street put a lot of pressure on the specific encounter and don't allow a more gradual "get to know you" phase. Do you have a social activity that you've neglected with the lack of available friends? Or one that you're interested in but never had the chance to get involved with? This is perhaps mundane advice, but check if there's a group that does that activity and try to become a regular. They're always very welcoming to newcomers and you'll find yourself well established in the group after a few returns.
