I see the distinctive yellow logo of "Česká pošta," which is the national postal service of the Czech Republic. The text on the signs confirms the language is Czech. The modern interior with a glass-covered walkway suggests a shopping arcade or a transit hub in a Czech city. I am fairly confident this is in the Czech Republic.

I suspect this is in Prague, likely within a shopping center or near a train station. I am 80% sure of this location.
