While the burgers aren't actually shaped like cubes (the name refers to the structure of the makeshift building just outside Harvey Norman in BTC City), they are served up quick, fresh and hot from the grill, and definitely hold their own against Ljubljana's ever-expanding field of burger joints. The menu has a selection of different burger options, such as chicken, roast beef, vegetarian and light (the latter served on a wholewheat bun with arugula), but for our money the Kraljevi (King) Burger can't be beat.
