  We embed a holographic description of a quantum field theory with Galilean
conformal invariance in string theory. The key observation is that such field
theories may be realized as conventional superconformal field theories with a
known string theory embedding, twisted by the R-symmetry in a light-like
direction. Using the Null Melvin Twist, we construct the appropriate dual
geometry and its non-extremal generalization. From the nonzero temperature
solution we determine the equation of state. We also discuss the hydrodynamic
regime of these non-relativistic plasmas and show that the shear viscosity to
entropy density ratio takes the universal value one over four pi typical of
strongly interacting field theories with gravity duals.
