Hong Kong ( CNN ) There 's a booming black market in Hong Kong , but it 's not for fake Apple Watches , or the iPhone . Instead , people are going crazy for tins of butter cookies . Tourists and locals line up around the block for several hours just to get their hands on Jenny 's cookies -- at $ 9 a tin . Its popularity has spurred bakeries to make and sell knockoffs , and the original store has signs warning against buying 'fake ' Jenny 's cookies . The tiny shop , located in Tsim Sha Tsui , one of the city 's main shopping districts , is swarming with people handing over wads of cash for the `` little bear cookies '' as they are known across Asia . People are even hired to stand in line to buy the goods and are later resold at a 70 % mark-up yards away , something the bakery also tries to discourage . A few meters away from the long cookie line , old ladies hold up paper signs advertising the cookies for sale . But when they see cameras approaching , they scurry away , only to reappear on another street corner . The frenzy in Hong Kong over the buttery treats is by no means an isolated example . In other parts of the world , food mania has erupted , swiftly winning people 's hearts and stomachs , only to fizzle out in a few months . From cronuts to ramen burgers , here are some foods that people around the world have spent hours of their lives waiting for . Were they worth it ?
