  As indicated by the recent data obtained by the T2K and the MINOS experiments
\theta_{13} can be large, even be comparable to the Chooz limit. Assuming that
it will be confirmed by ongoing reactor and accelerator experiments I discuss
its possible implications in the context of how to explore the remaining
unknowns in the lepton flavor mixing. While it opens wide range of
possibilities to explore CP and the mass hierarchy, I emphasize that the large
\theta_{13} allows us to take "all in one" (everything in a lunch box)
approach.
