A couple times a month there is a swing dance at Edgewood on Sundays. Frequently featuring a live band, there is a small cover charge (cash only) and a friendly atmosphere. The level of the dancers attending can be hit or miss but its a relaxing sunday evening. There is an area with tables, chairs and a snack table with beverages for an additional donation fee.
The parking can be difficult (it is a residential area), so it would be smart to try to get there early.
I believe they also have a dance lesson for beginners before the dance starts run by a group called Coal Country Traditions which is a Pittsburgh based group of older dancers that do swing dancing as well as folk dancing of different sorts, there always have pamphlets at the dance in regards to other dances and events going on within the city at a table in the back of the dance.
