A silver Airstream-style food truck, prominently featuring an illuminated "GROUND BURGER" sign in green letters on its roof, is positioned on a light-colored patterned cobblestone pavement in Lisbon, Portugal. A black circular decal on the truck's left side states "100% BLACK ANGUS BEEF". The right side of the vehicle is open, revealing a service counter with various menu boards. A wooden planter containing green foliage sits in the immediate foreground, to the right of the truck. Behind the food truck, three tall palm trees with green and brown fronds are visible, set against the backdrop of several buildings. One of these structures is a light grey residential building, identified by the signage "Residência Bom Sucesso ameis.pt", indicating the location is Praça do Bom Sucesso. A segment of a concrete wall and an older, lighter-colored building with a visible window and closed roller shutter are to the left. The sky above is clear and blue.
