American porn star James Deen has savaged the Sydney Opera House’s restaurant in a blog post, after dining there during his recent visit to Australia.

Deen was in Sydney for the annual Sexpo event, and dined at the Opera House on a recommendation.

The 28-year-old didn’t hold back in his online review, calling Opera Bar ''hands down the most god awful eatery in the existence of the universe''.

''Beautiful as the scenery was, this was the worst food I have ever eaten in my life,'' wrote Deen, saying he’d rather be ''forced to listen to Hanson and sing Creed'' than eat there again.

''Everything about this ‘restaurant’ is horrible. The system of ordering was stupid. You went to a bar and told them what you wanted. Then they stared at you when you said you haven’t chosen your seat yet,'' Deen wrote.

''After that you are given a number and forced to wait for [an] hour before a server comes over and b-----s at you for not telling them where you’re sitting EVEN THOUGH YOU ALREADY TOLD 4 DIFFERENT PEOPLE!!!!!!!''

Deen, who dedicated an entire episode of his web series James Deen Loves Food to ketchup tasting, then critiqued the food.

''It was so bad. My steak tasted like salt that someone p1ssed meat juice on,'' Deen wrote on his NSFW blog.

''The brussel sprouts were literally burnt to ashes. The risotto was actual soup. The pizza was basically grease on a cracker .... HOW DO YOU F--- UP PIZZA!!!!!????''

He continued: ''We actually had to leave and go to a different restaurant while I cursed their very existence and took off my pant.''

The award-winning porn star gave the Opera Bar one concession: ''Ambience was nice though.''

The Opera House in an official statement stood by its waterfront venue.

''Opera Bar is not only the most visited food and beverage venue at the Opera House, it is one of the most successful and celebrated bar and restaurant venues in Australia,'' the statement read.

''Named Best Bar in Australia by Australian Traveller magazine readers in both 2012 and 2013, its enduring popularity with both Sydneysiders and overseas visitors is a testament to its success over the past 13 years.''

When he isn't critiquing Australian venues, Deen works in the adult film industry. He has featured in more than 1800 movies over his career.

Not all of his movie roles are porn, however. Last year he played a lead role next to Lindsay Lohan in the Hollywood film The Canyons, directed by Paul Schrader.

Deen's first calling was porn, though. He told The Vine last year that he has never considered another line of work.

He loves his job so much he never takes a day off, but it's not just about filming scenes.

''I have a store and a website – jamesdeen.com – where you can buy videos, T-shirts, tank tops, sex toys, and I have a streaming video site, and there’s my blog which I update daily, so that’s always fun,'' Deen told The Vine.

''And doing scenes. I pretty much love all of it. It’s always nice to develop more as a brand, if you will, and absorb as much as possible," he said.

''Everything is great, so I never want to stop. My idea of a perfect day off is sitting in my office doing work. I never want to take a break.''
