**Title:** *Calabi-Yau compactifications of Landau-Ginzburg models for smooth Fano threefolds.*

**Abstract:** We discuss a way to compactify Landau-Ginzburg for Fano threefolds
presented as Laurent polynomials. This, in particular, gives a description of
"fibers at infinity" of the Landau-Ginzburg models. If time permits,
we discuss an explicit way to write down a Landau-Ginzburg model for any del
Pezzo surface of degree greater then 2 in terms of symplectic form
chosen on the del Pezzo.
