Costi Bros Seafoods

I just wanted to say a big thank you to Costi Bros on palm Sunday. Although we placed a large order on a fairly busy day, everything was cooked perfectly. Our guests were very pleased. Thank you to the team, I highly recommend for your local seafood fix!!

Best seafood in Sydney!!
I Always receive Exceptional seafood every single time. From the moment I stepped into the shop, I was greeted by the aroma of fresh ocean air and the sight of an impressive array of seafood. The staff were incredibly knowledgeable and helped me select the perfect catch for my dinner. I always look forward to a different selection of seafood every time I turn up to Costi seafood!!

Costi Bros Seafoods in Roselands for me is the best seafood not only in the Canterbury/St George district but all of Sydney.

I am a seafood lover and I must say not only does it beat everywhere on price but on quality as well. It makes sense once you see the queues outside the shop at lunchtime!

My wedding was on Saturday 27 May 2023 and they supplied the prawns and oysters for myself, my beautiful bride and our guests to enjoy. We had so many compliments on how fresh and delicious the prawns and oysters were! These compliments were coming from people who also owned fish shops!

Thank you to the entire team at Costi Bros Seafoods! You are the best of the best!

Costi Bros Seafoods are a family owned and operated business since 1978 sourcing and serving the finest and freshest local and regional seafood products.
Their selection is very vast and there's sure to be something to please everyone, from freshly shucked Sydney Rock & Pacific oysters from the oyster bar, pickled/marinated octopus in an authentic Mediterranean brine, smoked trout and live crab.
Costi Bros Seafoods post a weekly special though various social channels according to availability of seasonal catch, highly recommended is the grilled platter and selection of fresh salads to accompany your meal.
Well worth making a visit to this place, for the best service and high consistent quality seafood.
5 stars !

Great Seafood Store. It’s always fresh and at good prices. They can even cook any fish for you. And there’s a hot food area thats got some of the best fish and chips you’ll find in Sydney. Oyster and sashimi bar too. Overall an amazing seafood store.

I was impressed with the fresh quality and great variety of seafood at Costi Bros. Even though the shop was busy, their team worked very efficiently and everyone was so friendly. Would visit again if I’m around the area.

Costi Bros Roselands is the place to go to for all quality seafood. This family run business not only has freshest selection of seafood but you are always greeted with a smile.
I hosted a dinner party on the weekend and decided to cook seafood in our wood-fired oven. One pan of lobster tails and another of octopus.
The lobsters were cut in half for me and the octopus cleaned and cut as well. Hardly any preparation except for marinade and seasonings.
The result was amazing.
Dennis, Eleni and their sons really know seafood.
Highly recommend Costi Bros Roselands!

I'm so glad I purchased the seafood from Costi's for my birthday dinner! It was extremely fresh and of high quality. Not only this, the service was fantastic. Thank you Maria and Eve for your help with this. You made fantastic recommendations on what I should purchase, packed everything so well for me, and even took a bit of time to make a gorgeous sashimi flower for me. Thank you again ladies!

Highly recommend Costi Bros Seafoods!
Always greeted by cheerful and knowledgeable staff members.
The store display is always presented phenomenally and features the freshest seafood variety.
Thank you for the outstanding customer service.

Wonderful team that are very knowledgeable. I was looking all over George's River area for pippies and couldn't source live ones. My wife happened to stumble across Costi Bros seafood who had live pippies - they gave us pointers on purging them. They were all freshy and tasty.

My family was very impressed with the freshness of your seafood on New Year's Day.
I was served by Octa, she was very attentive & professional. The prawns she recommended were very fresh & delicious.
She was even kind enough to slice the sashimi for me.

Went to Costi Brothers for a quick bite and has 6 fish cocktails for $7.90 They were crispy and fresh and very very tasty and ready really quickly. I will be back to try the Oyster bar and the fresh fish options.

Ordered a seafood platter, on the weekend.
The prawns, were so tasty and delicious.
The greatest hit in my family was the fresh sashimi.
Fantastic job, to all the team for going above and beyond our expectations.

Well done team at Costi Bros Seafoods, you guys rock!
Came past Christmas Eve, initially I was disheartened because I was in the queue near Soul origin. Got to the counter in 9 minutes.
Bought the jumbo tiger prawns which were sensational, 2 local lobsters the best I've ever had! Waited for my kingfish sashimi to be freshly cut.
Out the door in 25 minutes.

Some the best customer service I’ve ever experienced I do believe the young fellow I was communicating with was Stefan not too sure about his last name. Definitely consider giving him a raise

Great variety of fresh seafood. Always a line here.. loooooong line! Ordered fish and chips and some seafood platter. Delicious!

Fantastic experience purchasing for Christmas. Great service and the queues weren’t too long. Granted we did arrive at 11:00pm!

Wow wow wow! Had this amazing sashimi platter for 8, amazing fresh & delicious!! And so abundant 8 hungry adults couldn’t finish it!

Always my go to when putting together a seafood platter feast. Their seafood is super fresh and great quality. One or two staff can sometimes come across a little bit rude/pushy when you want to pick particular fish rather than let them just grab whatever but you still get what you want. Not enough to deter me from coming back. They also always have lots of staff on so you never have to wait too long.

Their hot food/cook to order section is also great. I’ve ordered the grilled platter for two and it is very generous (easily serves two adult and two kids). My favourite is definitely the calamari - so tender and well cooked! Ask for chips on a separate platter to avoid getting soggy with extra chicken salt. We also like to pay $2 extra to upgrade our salad to one of the varieties in the window rather than a greek salad.
