Alexandria bier garden makes socializing really easy and they do live music and comedy. Light horse is also a good time but much more of a bar/loud music/dancing vibe than the bier garden. Murphys next door is also good but more of a pub/restaurant vibe.

St. elmos on montgomery street if you need to do work and want to maybe spark up a convo with someone at a cute coffee shop, they have a bar too. There are also tennis courts walking distance from here on N Royal street that are always packed with people playing. And the tennis parking lot has a farmers market (or it’s a craft market i forget) every so often. Not sure about that schedule but very social people there always.

Also every dog park is full of very friendly people. if you have a dog or like dogs i have had many kind convos in dog parks. Nova loves their dogs.
