Why did the burger-lover cross the road? To find one of the tiny toy chickens hidden near Byron restaurants this weekend. The eagle-eyed punter hunters who find the little birds and bring them into their nearest Byron will be rewarded with a free 'Clucky Balboa', the new chicken burger special. The sandwich sounds far from fowl: buttermilk-fried (or chargrilled) chicken breast, piled with guacamole, sriracha mayonnaise, pickled red onion, pickles and iceberg lettuce. Go ruffle some feathers.
