When I read the rugby sevens crowd was going to eat 12000 hamburgers on the weekend it made me think how the humble burger (particularly Mac - burgers) are often targeted by critics of the fast food industry.
On the other side advertisers try various approches to make us eat more. If you want to get away from mass production and the products of Hamburger University try the Lembastic burger from Lembas Cafe in Raumati South (Now named Raumati Social Club) which took out the title of Wellington’s best burger.
If you are looking for an inspiration for the BBQ try this hamburger recipe from Ruth Pretty. Wouldn't it be great for stadiums to have this standard of food.
