  We revisit the computation of the shear viscosity to entropy ratio in a
holographic p-wave superfluid model, focusing on the role of rotational
symmetry breaking. We study the interplay between explicit and spontaneous
symmetry breaking and derive a simple horizon formula for $\eta/s$, which is
valid also in the presence of explicit breaking of rotations and is in perfect
agreement with the numerical data. We observe that a source which explicitly
breaks rotational invariance suppresses the value of $\eta/s$ in the broken
phase, competing against the effects of spontaneous symmetry breaking. However,
$\eta/s$ always reaches a constant value in the limit of zero temperature,
which is never smaller than the Kovtun-Son-Starinets (KSS) bound, $1/4\pi$.
This behavior appears to be in contrast with previous holographic anisotropic
models which found a power-law vanishing of $\eta/s$ at small temperature. This
difference is shown to arise from the properties of the near-horizon geometry
in the extremal limit. Thus, our construction shows that the breaking of
rotations itself does not necessarily imply a violation of the KSS bound.
