Good bars for the older crowd (mid 30s to mid 50s)?

Relatively new to the area and recently single guy (early 40s) wondering which bars/lounges would be good for an older crowd? I'm looking for a cool, chill place to mingle and just socialize.

BTW, where do the single people in this age range hang out to meet others? Just trying to find some fun options to meet new people and hopefully find a great lady without using the dreaded "apps".

Any suggestions much appreciated!
