There’s a Philly Girls Who Walk group that gets together maybe once or twice a month - I’ve never gone but seems like it could be a way to make friends. They have an instagram page, even if you aren’t on social much you could check the page from time to time to see what’s coming up? You could also check out the free library’s culinary center (food-related workshops and events), or something like a class at the new Philly Cheese School.
