  This is a review of the theory of toric Landau-Ginzburg models - the
effective approach to mirror symmetry for Fano varieties. We mainly focus on
the cases of dimensions 2 and 3, as well as on the case of complete
intersections in weighted projective spaces and Grassmannians. Conjectures that
relate invariants of Fano varieties and their Landau--Ginzburg models, such as
Katzarkov-Kontsevich-Pantev conjectures, are also studied.
