I think it's more on scale with the original buildings, like KBurger, Pet Store, Moe's, etc. I think that's why it fit so well on my town square next to Zesty's.
Sometimes i feel like there's two designers making buildings. One insisting on the smaller scale, and one trying to make things bigger. That person is who made all of the SH buildings i imagine.
But i think the winner for smallest scale relativity is the Helter Shelter, which actually changed after release and shrunk significantly. It's so stupid looking now, but made for great ironic joke that all aid to the poor is being scaled back, including physical objects.
