  We discuss the behavior of Landau-Ginzburg models for toric orbifolds near
the large volume limit. This enables us to express mirror symmetry as an
isomorphism of Frobenius manifolds which aquire logarithmic poles along a
boundary divisor. If the toric orbifold admits a crepant resolution we
construct a global moduli space on the B-side and show that the associated
tt^*-geometry exists globally.
