We're torn about what to do tonight after work: Center City Sips or Summer Nights at the Museum? The University’s Museum of Archaeology holds a concert series all summer long on Wednesday nights from 5 to 8 pm. Tonight, the West Philadelphia Orchestra is playing their eclectic mix of music. Admission is $10 unless you hold a PennCard in which case it’s free. Since it will be such a beautiful evening, this is definitely where I’m going!
