  We extend the stringy derivation of N=2 AdS4/CFT3 dualities to cases where
the M-theory circle degenerates at complex codimension-two submanifolds of a
toric conical CY4. The type IIA backgrounds include D6-branes, and the dual N=2
quiver gauge theories contain chiral flavors. We provide a general recipe to
derive the geometric moduli space of flavored versions of Abelian toric quiver
gauge theories. The CY4 cone is reproduced thanks to a non-trivial quantum
F-term relation between diagonal monopole operators and bifundamental fields.
We find new field theory duals to many geometries, including Q111.
