Warped extra dimensions admit a nice interpretation through the prism of the gauge/gravity correspondence. Any well thought out phenomenological scenario based on extra dimensions must supply a controlled description of the dynamics among the extra dimensional modes, and of their interactions with Standard Model particles. A most convincing way of specifying these dynamical rules is via a consistent realization of the given extra dimensional scenario within string theory. A natural way of achieving this goal is by having the Standard Model emerge at the IR bottom of a duality cascade. We discuss general aspects of this framework. We illustrate our ideas with an explicit example. Interestingly, there is a range of energies in which we are able to provide a rather explicit gravity dual.
