TV and legs
The door area looks the same, but the rest of the layout is not. OUAT is shot in Vancouver and GG was shot on the WB Backlot in California, so I doubt sets were actually reused, especially since it's two different channels and two different production companies. Stars Hollow and Storybrooke (the setting of OUAT) are two small northeastern towns though, so it would make sense that the two would look similar? Plus, some set designers might have worked on both.
