Moo Gourmet Burgers is at 232 King Street, Newtown. One wall is dominated by a giant multicoloured painting of a cow and there's a sunny courtyard with seating out the back. The burger menu is extensive: I had the piri piri chicken burger ($15) accompanied by delicious chunky chips. We also tried the Moo-teaser milkshake ($6.50), an incredibly rich, gooey concoction of maltesers, ice cream, chocolate syrup and malt. The star of the show, though, was the Big Moo burger ($16): a mind-boggling tower of angus beef, cheese, beetroot, pineapple, bacon, lettuce, tomato, egg, mayo and tomato relish. The only way to eat the burgers is to hold on with both hands.
