  A recent analysis of the Fermi Large Area Telescope data provided evidence
for a high-intensity emission of high-energy gamma rays with a E^-2 spectrum
from two large areas, spanning 50{\deg} above and below the Galactic centre
(the "Fermi bubbles"). A hadronic mechanism was proposed for this gamma-ray
emission making the Fermi bubbles promising source candidates of high-energy
neutrino emission. In this work Monte Carlo simulations regarding the
detectability of high-energy neutrinos from the Fermi bubbles with the future
multi-km^3 neutrino telescope KM3NeT in the Mediterranean Sea are presented.
Under the hypothesis that the gamma-ray emission is completely due to hadronic
processes, the results indicate that neutrinos from the bubbles could be
discovered in about one year of operation, for a neutrino spectrum with a
cutoff at 100 TeV and a detector with about 6 km^3 of instrumented volume. The
effect of a possible lower cutoff is also considered.
