  The entropy of a BTZ black hole in the presence of gravitational Chern-Simons
terms has previously been analyzed using Euclidean action formalism. In this
paper we treat the BTZ solution as a two dimensional black hole by regarding
the angular coordinate as a compact direction, and use Wald's Noether charge
method to calculate the entropy of this black hole in the presence of higher
derivative and gravitational Chern-Simons terms. The parameters labelling the
black hole solution can be determined by extremizing an entropy function whose
value at the extremum gives the entropy of the black hole.
