Moonlight Express in The Strip is the home of what is possibly the finest egg roll in the city. It’s also possibly the great grand-pappy of Pittsburgh food trucks. I remember it being parked between Hillman Library and CMU.
Anyway, they served fantastic egg rolls then, and they serve fantastic egg rolls now.
And, No. I don’t think this food truck runs anymore, but it is permanently located in a vacant lot in the Strip District between Parma Sausage and the old Feinsteins.
If you’re in the city, just go. You’ll be happy.
