Tip Nº 01
Biedronka on Grobla III is 6 minutes from Dzien Dobry and 8 minutes from the Old Town hostels, open until 22:00 daily. Mondays and Thursdays have the widest produce selection — Saturdays are picked over by mid-afternoon. Lidl near Targ Rybny is a minute further but has better bread.
Tip Nº 02
For Polish-specific cooking (pierogi, zurek, bigos), buy the dough and filling at Hala Targowa market rather than trying to sculpt from Biedronka ingredients. Pre-made frozen pierogi at the market run 15-20 PLN per 500g, enough for two people, and just need boiling. Sauerkraut and kielbasa sausage for a proper bigos stew are 20 PLN together.
Tip Nº 03
Don't buy fresh fish at Biedronka — go to the Targ Rybny fish market (10 min walk from any Old Town hostel). Baltic cod is 40 PLN/kg, flounder 35 PLN, open until 15:00. If you're at Rakietka in Wrzeszcz, the market on Hala Targowa is better than trekking to Targ Rybny.
Tip Nº 04
Bring your own small pouch of olive oil, salt and pepper. Hostel kitchen spice shelves are unreliable — the Dzien Dobry and Rakietka shelves are stocked, the World Hostel and Za Murami shelves are usually empty. A 50ml travel bottle of olive oil transforms the cooking options.
Tip Nº 05
Use the kitchen as a social tool. The Moon Hostel and World Hostel long communal tables fill by 19:30 every evening. Cooking a pasta that feeds six and sharing is the cheapest way to meet travelers in a hostel — it converts a 15 PLN tomato can into the most-remembered dinner of your Gdansk trip.
