We compare the cohomology ring of the flag variety $FL_n$ and the Chowcohomology ring of the Gelfand-Zetlin toric variety $X_{GZ}$. We show that$H^*(FL_n, \mathbb{Q})$ is the Gorenstein quotient of the subalgebra $L$ of$A^*(X_{GZ}, \mathbb{Q})$ generated by degree $1$ elements. We compute thesealgebras for $n=3$ to see that, in general, the subalgebra $L$ does not havePoincare duality.
