In this talk I present a novel and very efficient description of
spacelike warped Anti-de Sitter black holes in terms of a lower spin
Chern-Simons theory that allows for various interesting extensions. A
special focus will be on how to determine the thermal entropy as well
as entanglement entropy holographically in this formulation. The
validity of the results obtained in the Chern-Simons formalism will be
verified by providing an additional metric interpretation.
