A women's rights group has slammed a popular eatery  for their latest advertising campaign which they claim objectifies women's bodies to sell beer. The Lowenbrau Keller, in Sydney's The Rocks, has released a social media and bus campaign featuring the slogan 'Wunderbra' underneath a photograph of a woman in a low-cut lederhosen holding a tray of beer steins. The same campaign also features an image of two women in a similar state of dress with the caption 'Make Mein A Dubbel', sparking outrage from Collective Shout, who claim the advertisements reinforces sexual objectification. Scroll down for video . Campaign group Collective Shout has slammed Sydney restaurant Lowenbrau Keller for an advertising campaign they claim sexually objectifies women . The Lowenbrau Keller campaign is being used on both social media and public transport platforms . 'Through this advertising Lowenbrau reinforces sexist attitudes and invites patrons to view female staff as sexual objects, exposing them to sexual harassment,' Melinda Liszewski, spokesperson for grassroots campaign movement Collective Shout, told Daily Mail Australia. '[The company's slogan] “Live it Large” and “Wunderbra” sends the message to an audience of all ages that women are to be valued for their body parts,' Ms Liszewski said. Ms Liszewski said that the 'Make Mein A Dubbel' advertisement also suggests that the two women shown are 'part of the menu'. Dan Hopkirk, Marketing Director for Urban Purveyor Groups who owns the Lowenbrau Keller, said that the advertisements were meant as 'fun play-on words' that people would be familiar with. '[The campaign was] designed as a portrayal of the typical Bavarian cultural experience enjoyed by millions during Oktoberfest in Munich every year, synonymous with this venue,' Mr Hopkirk said. 'The advertising slogans coupled with the imagery that has been used across the campaign, are popular anglicised German phrases which are fun play-on words,' he said. 'The Löwenbräu Keller campaign aims to embody the traditions of Oktoberfest which is about a celebratory occasion and enjoyable time spent with friends.' Ms Liszewski said that the Lowenbrau Keller, along with other establishments which the Urban Purveyor Group owns, including the Bavarian Bier Cafe, has a history of creating sexist and objectifying advertisements. 'A number of Lowenbrau advertisements make a direct comparison between the serving size of food and beverages and the size of women’s breasts,' she said. Ms Liszewski said that the advertisement also suggests that the two women shown are 'part of the menu' This images was tweeted from the restaurant's official Twitter account and posted to their Facebook page with the caption 'Is anybody suddenly thirsty?' The advertisements have garnered criticism from social media users who expressed their outrage over the allegedly objectifying images . 'This is explicitly spelt out via an ad on social media “Bigger is better - don’t you agree? We’ve got big biers, big meals and big…fun. #beer” and reinforced by outdoor advertisements.' The image, which shows a woman's chest next to steins of beer, was tweeted from the restaurant's official Twitter account, and was also posted to their Facebook page with the caption 'Is anyone else suddenly thirsty for a bier?'. The advertisements have garnered criticism from social media users who expressed their outrage over the allegedly objectifying images. 'Wie Sexistisch. If that is the attitude you wish have about your restaurant, then I wont be visiting it again! Guten Tag!' posted one social media user after the image was posted onto the Lowenbrau Keller Facebook page. One Twitter user uploaded a photo of the current 'Wunderbra' advertisement after spotting it on the back of a bus. 'I'm glad these advertisers drew the line before they went tasteless,' the social media user joked. According the Advertising Standards Board code, advertisers are prohibited from presenting men or women in a way that is sexually 'exploitative and degrading'. However, in 2007 the Lowenbrau Keller was reported to the Board for a previous campaign which showed a man dressed in traditional Bavarian clothing staring down the front of a woman in a low-cut lederhosen who is holding two steins of beer. The Board dismissed the complaint due to the 'ambiguity' of the claim that the man was shown to be staring at the woman's breasts, but ruled that the advertisement emphasised the woman's breasts and 'this did objectify the woman'. 'I'm glad these advertisers drew the line before they went tasteless,' a social media user joked when he posted this image to Twitter after spotting the ad on the back of a bus . 'Viewing these advertisements it is hard to believe it is 2015,' said Ms Liszewski . The Lowenbrau Keller responded to the claims and said that 'the last impression we want to give is that you can come to our restaurant and stare at our waitresses' breasts, and we have very strict house rules for anyone in our restaurant exhibitingoffensive behaviour.' However, Ms Liszewski said that the active social media media presence the restaurant had allowed fans of the establishment to express sexually harassing comments. 'Comments posted by fans on social media demonstrate this - “Big t*ts” …. “very nice jugs” … “this is what you will see on Saturday night big ass “beers” can’t wait",' she said. In 2013, the Urban Purveyor Group released an ad for Oktoberfest, which is held in both the Lowenbrau Keller and the Bavarian Bier Cafe each year. The clip depicts 'Bavarian beauties training for Oktoberfest', clad in short shorts and crop tops as they run along the beach and the camera pans up and down the women's bodies. 'Viewing these advertisements it is hard to believe it is 2015. There is a growing awareness in the community that sexual objectification and sexist attitudes underpin the epidemic of violence against women in Australia,' Ms Liszewski said. Ms Liszewski said that the active social media media presence the restaurant had allowed fans of the establishment to express sexually harassing comments . The Advertising Standards Board advised that the Bavarian Bier Cafe removed the above ad after it was slammed for sexually objectifying women and comparing them to pieces of meat . 'The Urban Purveyor Group and associated restaurants need to get out of the dark ages and start treating women and girls with the respect they deserve.' Last year, the Bavarian Bier Cafe was forced to remove their campaign advertising their new range of ribs, after the ads were attacked for objectifying women. The Advertising Standards Board advised that the Cafe removed the ads, which depicted a fully clothed man with two women in low cut dresses on either side, in front of a rack of ribs with the slogan 'We've got the best racks'. The cafe claimed that for every serving of the ribs sold, the company would donate $1 to Treasure Chest Charity, a group which raises money for breast reconstruction for women who have suffered through breast cancer. 'Women are literally being referred to as a piece of meat,' Ms Liszewski said. 'The ad is inviting us to judge women by the quality of their breasts. It's bad enough that there is an opinion in the general community that this is what women are worth, but to link it to a breast cancer charity is just another layer of objectification.'
