This pop-up restaurant has been touring Europe rooftops since last April and is currently perched on top of the Royal Festival Hall in London.
The structure's white aluminium exterior is made up of jagged forms to accentuate its unnatural position as a parasite on existing landmarks.
The first installation of the restaurant was in April last year in Brussels, over the 19th century Cinquantenaire Arch. The Cube then travelled to Milan where it overlooked the cathedral from a rooftop in Piazza del Duomo.
The Cube will remain on the Royal Festival Hall until September 30. A twin structure will also be sitting on Stockholm's Royal Opera House until October 21.
