  We consider generalized gravitational entropy in various higher derivative
theories of gravity dual to four dimensional CFTs using the recently proposed
regularization of squashed cones. We derive the universal terms in the
entanglement entropy for spherical and cylindrical surfaces. This is achieved
by constructing the Fefferman-Graham expansion for the leading order metrics
for the bulk geometry and evaluating the generalized gravitational entropy. We
further show that the Wald entropy evaluated in the bulk geometry constructed
for the regularized squashed cones leads to the correct universal parts of the
entanglement entropy for both spherical and cylindrical entangling surfaces. We
comment on the relation with the Iyer-Wald formula for dynamical horizons
relating entropy to a Noether charge. Finally we show how to derive the
entangling surface equation in Gauss-Bonnet holography.
