Three dimensions provide a useful playground to study gravity and
higher spin generalisations thereof. Black hole solutions and the
corresponding entropy can be studied, and holographic aspects can
be investigated. The known interacting higher spin gauge theories
are formulated in a frame-like formalism using generalised vielbeins
and spin connections, and standard tools from metric-like
formulations like e.g. Wald's entropy formula cannot be applied. I will
review recent progress in the metric-like formulation of a spin-3 field
coupled to gravity that corresponds to an SL(3)xSL(3) Chern-Simons
theory. At the end I will discuss how this can be used to compute
corrections to the entropy of a higher spin black hole.
