I agree with you. An MBA there could open new interesting challenges, but doing it in a good school is the key.
A couple of programs, both in Warsaw, seemed interesting:
the MBA offered by the Warsaw University of Technology business School and the one offered by the Warsaw School of Economics.
even if with strong parternships with very good school in the west, that programs are still young but, I think, up and going.
words warning, both of these schools are very quantitative!
Especially the second one, if you are not adept and good with numbers you will simply not survive. most of graduates from Warsaw School of Economics work for top banks/consulting firms etc either in local Warsaw offices or London, Tech graduates usually end up in quant finance somewhere.
as a foreigner it might be easier to get in, but for locals its almost impossible unless you are gifted and did well in math/physics/economics olympics.

What i also find interesting is that its Polish and Russian Universities almost always 1-3 even though all the top schools of the world are competing. MIT, Cal Tech, Princeton, Carnegie Mellon, Berekeley, have never beat them.
