The pizza restaurant is La Fosse. It took the production team a while to find a restaurant that would require minimal set dressing but would be willing to close for a day. The team filmed at La Fosse on 22 August. The area underneath the London Eye where the Doctor and Rose confront the Nestene Consciousness was filmed in an unused paper mill in Grangetown, Cardiff. It underwent steam cleaning because there were such high health and safety concerns. They were only permitted to film for three days, which required that some of the sequence be cut: originally, there was to be another Auton Mickey involved. Filming took place at the paper mill from 23 to 25 August. The scene where Rose joins the Doctor is at St David's Market, filmed on 26 August.
