  Motivated by the recent progress on gravity duals of supersymmetric
Chern-Simons matter theories, we consider classical membrane solutions in AdS_4
x M^{1,1,1}. In particular, we present several types of exact solutions
rotating in the Sasaki-Einstein 7-manifold whose isometry is SU(3)xSU(2)xU(1).
We analyze the limiting behavior of macroscopic membranes and discuss how one
can identify the dual operators and the implications of our result on their
conformal dimensions.
