Gourmet Burger Kitchen is a restaurant chain in England and Wales specialising in, as the name suggests, gourmet burgers.GBK, as it's known, was developed by three New Zealander chefs living in London who missed the way food tasted in NZ where gourmet burgers are a favoured good quality convenient food. One of those chefs was Peter Gordon who has also designed menus for Air New Zealand and his own restaurant The Providores in London. The New Zealand heritage is in evidence in the shape of the 'kiwiburger', a burger which contains the unusual ingredients beetroot, pineapple and a fried egg. See alsoNew Zealand Cuisine
