  A new infinite class of Chern-Simons theories is presented using brane
tilings. The new class reproduces all known cases so far and introduces many
new models that are dual to M2 brane theories which probe a toric non-compact
CY 4-fold. The master space of the quiver theory is used as a tool to construct
the moduli space for this class and the Hilbert Series is computed for a
selected set of examples.
