The café Villanelle is standing outside (when she reads the note in the painkiller box) has just been renovated on another BBC show Interior Design Masters (2019)
As Villanelle drinks from a bottle of water and reads the note from Konstantin's previous trainee, Gunn, she is standing in front of a real restaurant, called "Olby's," (as painted on the door glass), in the British seaside town of Margate. It was subsequently renovated on series 3, episode 6 of another BBC show, Interior Design Masters (2019). Although this and that episode both aired in 2022, Killing Eve, completed filming in November of 2021, while the renovation was done in 2022. (Reality shows require less time in post-production.) As of May, 2024, both shows stream in the US on Netflix.
