For me 25 PLN is expensive for Polish standards. I am sure for the Brits here this is good value for money
It sounds pretty expensive when you compare it to UK prices, but then everywhere in the UK is nearer to the sea than Warsaw is ;)
This place: homeofthejumbocod.co.uk/#/welcome/4517957101
is effectively my "local" ( even though it's not really that local) and sells the best fish and chips in the world. The fish is at least 12" long, and the portion of chips is huge; I can't finish it. And all this for just 18,31 PLN at today's exchange rate :)
Despite yesterday's sickening "toxic fish" thread, I've not been put off - Yo! Sushi at lunchtime, fish 'n' chips from the above for dinner :D
