Great report.
It is actually not that unusual for department stores to have food markets. In the old days (I know, I am dating myself) most US department stores had food courts that had absolutely nothing in common with todays mall food courts. Dayton's and Donaldson's in Minneapolis, Carson Pirie Scott in Chicago, Macy's in NY all had elaborate food operations.
Today you can still find fancy food courts at Printemps and Galeries Lafayette in Paris, KaDeWe in Berlin, a lot of the Ginza district department stores in Tokyo, and probably many more that I have yet to explore.
