I consider a theory of flavor in which standard model fermions transform under a chiral SU(3)_L x SU(3)_R horizontal gauge symmetry, broken to a U(1) subgroup whose associated Z' gauge boson can explain the observed anomalies in B->K l l decays.  To satisfy ATLAS dilepton and perturbativity constraints, the Z' mass should be not far above 5 TeV, hence close to discovery at LHC.  New contributions to B-\bar B and K-\bar K mixing are not much below current limits, and possibly also lepton-flavor violating decays mu -> 3e, tau -> 3l.
