  A brief review of recent studies on suppression of bottomonia in an
anisotropic quark-gluon plasma created in heavy-ion collisions at the LHC is
presented. A reasonable agreement between the model predictions for the
inclusive $R_{\rm AA}$ suppression factor and the preliminary CMS experimental
data is found. The values of the shear viscosity to the entropy density ratio
extracted from the comparison with the data lie between one and two times the
gauge/gravity duality lower bound. These values agree very well with the fluid
dynamical fits to the light hadron correlation data and confirm that the
quark-gluon plasma is a nearly-perfect fluid.
