I decribe an attempt to construct a QCD-like theory with a gravitational dual. A theory with the IR gauge fields of non-supersymmetric Yang Mills theory is constructed by deforming the AdS/CFT Correspondence. The geometry is shown to describe a confined glueball spectrum with a mass gap. Wilson loops in the theory appear to describe QCD-string breaking. Finally we discuss the addition of quarks by the inclusion of D7 brane probes. In a simple deformed geometry we show that chiral symmetry breaking and a massless pion are predicted.
