The author proposes a stationary phase integral formula for the restricted \(Gr_{m,N}\)-Whittaker function \(\Psi^{(m,N)}_{\underline{\lambda}} (x,0,\dots ,0).\) He uses a generalization of the standard Whittaker model for principal series representation for \(\mathfrak{U}(\mathfrak{gl}_{N})\), and its realization in the space of totally positive unipotent matrices. For part I, cf. [the author, ``On parabolic Whittaker functions'', \url{arxiv:1011.4250}].
