We only had one day in Pittsburgh and we decided to visit the Science Center. It was amazing. I enjoyed the robot that could shoot basketballs and the model train village set. Extremely family-friendly, a wide variety of exhibits, and all-around fun! Highlights include the decommissioned submarine docked alongside the building and the new Robotics exhibit, and the variety of bicycles from different eras.This museum is very clean and has very friendly staff.
