This is GUM - The Major Department Store as it was called in the Soviet times. It bases in the heart of Moscow - Red Square.
It's like KaDeWe in Berlin.
For nowadays mostly it's a place of interest instead of shopping because not everyone can effort it. The atmosphere is very nice. You can taste its famous ice-cream and enjoy a nice walk through its streets. Finally you shall visit the Gastronome №1, where you'll find the delicious food. The greatest impressions!
Surely you like it!
