A pub has been slammed for a 'sexist' advertising poster that is offering free meals for 'hot' women.

Petersham Inn in Sydney's inner west launched the 'hot girls eat free' promotion in an attempt to attract more female customers to the pub.

But the 'light-hearted' advertising poster plastered on the outside of the pub has since faced public backlash with some labelling it 'sexist' and 'misogynistic'.

Petersham Inn in Sydney's inner west has been slammed for being 'sexist' after launching a 'hot girls eat free' promotion in an attempt to attract more female customers to the venue

The poster features a woman seductively eating a slice of pizza with the slogan 'hot girls eat free'.

'Totally appalled! That is absolutely outrageous in this day and age,' one woman wrote on Facebook.

'It's offensive and wrong. How do I explain it to my two daughters?' another said.

One mum wrote: 'Both my teenage sons pass this sign while walking to school... what kind of message is this sending?'

Petersham Inn was formerly a family-friendly pub but recently transformed into an American-style sports bar with a 'gentleman's club' complete with topless waitresses and strip shows.

The issue was raised on Nine's Today Extra show during a panel discussion between the hosts on Wednesday following the public backlash.

Newsreader Amelia Adams admitted she wasn't at all outraged by the poster and said she has never been one to turn down a free meal.

'I am not outraged at all. Is it a bit tacky? Yes, it is. Is it a bit sexiest, probably. It is a gimmick,' she said.

'My main concern was how do you police who is hot or not? I'm thinking that could be very damaging for any young woman who goes in and isn't considered hot enough.

'Everyone gets served. That's the whole thing. You go up to the bar, you order, the staff say, "OK, you're hot."

'I heard the licensee on radio last night. It is just a bit of fun publicity and, you know, quite frankly, if I wasn't working today, I'd be going there for lunch.'

Bianca McDonald, who took over as the venue's licensee in June, defended the promotion and said it was meant to be a 'creative and funny' way to attract women into the bar.

'The sign was meant to be lighthearted and tongue-in-cheek and to create a spirit of fun for the patrons, as well to bring local women into the pub,' Ms McDonald told the Inner West Courier.

'There are so many boring signs out there, why not have a bit of fun with it all?'
