  Using the duality conjecture between N=6 supersymmetric U(N)_k \times
U(N)_{-k} Chern-Simons theory and M-theory on AdS_4 \times S^7/Z_{k}, we
calculate the corrections to the shear viscosity of the field theory at
temperature T. At strong 't Hooft coupling and at small k level, we have
considered one-loop correction to the M-theory effective action. At large k
level, we have considered the alpha' correction to the type IIA effective
action. In both cases the correction to the ratio of shear viscosity to the
entropy density is positive.
