  In this paper we investigate properties of Chern-Simons theory coupled to
massive fermions in the large N limit. We demonstrate that at low temperatures
the system is in a Fermi liquid state whose features can be systematically
compared to the standard phenomenological theory of Landau Fermi liquids. This
includes matching microscopically derived Landau parameters with thermodynamic
predictions of Landau Fermi liquid theory. We also calculate the exact
conductivity and viscosity tensors at zero temperature and finite chemical
potential. In particular we point out that the Hall conductivity of an
interacting system is not entirely accounted for by the Berry flux through the
Fermi sphere. Furthermore, investigation of the thermodynamics in the
non-relativistic limit reveals novel phenomena at strong coupling. As the 't
Hooft coupling approaches 1, the system exhibits an extended intermediate
temperature regime in which the thermodynamics is described by neither the
quantum Fermi liquid theory nor the classical ideal gas law. Instead, it can be
interpreted as a weakly coupled quantum Bose gas.
