  We study special Lagrangian cones in $\C^n$ with isolated singularities. Our
main result constructs an infinite family of special Lagrangian cones in $\C^3$
each of which has a toroidal link. We obtain a detailed geometric description
of these tori. We prove a regularity result for special Lagrangian cones in
$\C^3$ with a spherical link -- any such cone must be a plane. We also
construct a one-parameter family of asymptotically conical special Lagrangian
submanifolds from any special Lagrangian cone.
