Where to buy seafood in Warsaw?

I used to buy mussels in Kuchnia Świat in Arkadia...But they do not sell them anymore.
Carrefour is doing that now these days, but I do not trust them at all, they are perfectly willing to give a food poisoning.
So...where I can I buy in Warsaw mussels on Thursday / Friday?

There's a shop close to the bottom end of ul. Poznanska, on the west side of the street. They sell frozen mussels and other seafood..

I recently discovered (when I was looking for mussels) a great shop called Le Maree. Mussels were top quality, unfortunately the price was also top :)

Anyway I recommend it for prime quality fish and seafood.

if you are going to risk it, try going on Thursday as most supermarkets get fresh deliveries on Thursday in time for the Friday fish fest

discard any which will not close when you give them a gentle tap and if one will not open after you have boiled them, leave it well alone

That is why I can recommend this outfit. They are much more expensive as any supermarket, but the smell emanating from the Carrefour fish counter in Arkadia (which I suppose could be one of the better ones)...

Somewhere near the Wisła River? ???

Bomi at Klif has a decent selection......

Fish stinks anyway unless you buy it right from fishermen or if you put it in water with lemon like the Japanese do.
Also do not forget that those stores own their own boats but Fresh fish is never really fresh, it's always 15 days old anyway because the ships must sail further and further away to fishing zones .

I am surprised that Carrefour in Warsaw is not great, they would never risk any food poisoning though for they could go out of business.

Alma Supermarket has good fresh fish( smelly too but ok it we don't turn them into sushis) but their selection is really scarce.(Salmon Herring Salmon Herring Carp for Christmas and trout from time to time)
