Give a man a burger and you'll feed him for lunch. Give a whole office free burgers and you'll find at least one man amongst them who'll spare 5 minutes from the coalface to gratuitously plug the burgers everyone's chowing down on. Particularly when it's all for a good cause...

GBK have just launched a charity partnership with their Kiwi Burger. Find yourself munching on one and not only will you be lining your stomach, you'll also be doing your bit to help save the endangered Kiwi in New Zealand. Why? Because GBK are donating 25p from each Kiwiburger sale to the Whakatane Kiwi Trust. Nice chaps that they are.

They're also launching three other non-charitable new burgers; the wellington, the beef and the chicken Babaganoush. Not forgetting the re-introduction of the Jamaican buger. All of which are mighty tasty, of course, but even more so when they're free - thanks very much burger-lady!
