Located on Carson Street in the business district of Southside, Cosmo is making quite the name for itself as being one of the best exclusive night lounges in Pittsburgh. Established in early 2019, it didn’t take long for Cosmo to gain popularity among the nightlife in Southside before reaching sold out weekends. From hosting DJs from out of town to putting on extravagant performances, Cosmo is the place to be no matter what night of the week it is.
