The traffic signs, particularly the circular "no entry" and "stop" signs, are consistent with European standards. The design of the underground parking garage, with its specific green wall markings and metal railings, looks very familiar to modern urban developments in Poland. The signage style strongly points towards a Polish city. I am moderately sure about this location.

The sign clearly says "CHR Złote Tarasy," which is a major shopping center in Warsaw, Poland. The language is Polish, and the signage confirms I am in the underground parking facility of this specific mall. The environment is consistent with the interior of a large, modern urban parking garage. I am now very confident in this location.
