A top Sydney chef exploded online after receiving a number of orders with 'false' allergies.

Sydney's Queen Chow head chef Patrick Friesen posted a photo to Instagram with 12 meal orders, all with supposed allergies.

'Can people with dietary requirements start knowing what you can and can't eat?' Friesen posted alongside a picture of people's orders.

The Queen Chow head chef (pictured) said customers had 'shellfish allergy but loves oyster suace' and were 'gluten free but loves gluten as long as it's not a piece of bread'.

'Shellfish allergy but loves oyster sauce,' he said.

'Gluten free but loves gluten as long as it's not a piece of bread.

'Vegetarians that love a chicken wing.

'Pescatarians who eat chicken.'

The head chef's annoyed post received more than 700 likes and more than 70 comments from people agreeing with the ridiculous dietary requirements.

With many diners announcing they had allergies, simply because they don't like a certain food or are on a certain diet, the top chef said it makes a life difficult for people who actually suffer allergies.

'Sort your s*** out and let your waiter know,' Friesen posted.

Friesen has posted about customer order frustration online before, sharing high maintenance burger orders (pictured)

'You make it real damn hard for people with actual allergies and dietaries to go out to eat.'

While the chef has posted about his recent frustrations with picky diner's demands, it is not the first time the top chef has exploded online.

In 2014, the Hong Kong street food inspired chef shared his frustration about one fussy eater's high maintenance burger order.

The customer required the burger to be 'well done, no tomato, lettuce, pickle, onion, sauce and mayo on side, tree nut and tomato allergy, cut in two'.

Again in 2014, the top chef exploded on Instagram with another food order from vegetarians.

The docket showed four dishes all required to be vegetarian, but Friesen appeared to be slightly offended.

'Hey vegetarians, can you think about (it) before you come to a BBQ restaurant and demand we change a bunch of dishes just for you,' he posted.

'I don't go to an Indian restaurant and get pissed off they serve curries. F**.'

Friesen posted the most recent rant out of frustration because his mother, a coeliac disease sufferer, had a genuine intolerance to wheat, rye, barley and oats, he told News Corp.

'You have these people who come in on a first date and they say 'I'm allergic to onions' because they just don't want to have onion breath,' he said.

'And for the kitchen it can be torture. Especially when we have real allergies to be concerned about.'
