We consider 3-dimensional toric Calabi-Yau singularities which arise as cones over the Chow quotient for a torus acting on projective space. We show that the Chow forms of the closures of the codimension 2 orbits can very easily be written down from the quiver with superpotential which corresponds with the given CY3 singularity under the correspondence between CY3 singularities and quivers with superpotential which is part of the AdS/CFT correspondence in physics. We also prove that this provides a new method for computing the principal A-determinant in the theory of Gelfand-Kapranov-Zelevinsky.
