  Electrons in quantum matter behave like a fluid when the quantum-mechanical
carrier-carrier scattering dominates over other relaxation mechanisms. By
combining a microscopic treatment of electron-electron interactions within the
random phase approximation with a phenomenological Navier-Stokes like equation,
we predict that in the limit of high temperature and strong Coulomb
interactions, both monolayer and bilayer graphene exhibit a universal behavior
in dynamic viscosity. We find that the dynamic viscosity to entropy density
ratio for bilayer graphene is closer to the holographic bound suggesting that
such a bound might be observable in a condensed matter system. We discuss how
this could be observed experimentally using a magnetoconductance measurements
in a Corbino geometry for a realistic range of temperature and carrier density.
