More places now offer filled potatoes but ‘Under the Fish’ continues to serve the best in town in our opinion. For less than 30zł, diners get a 350g baked potato, split open, stuffed with a filling of their choosing (salmon, tuna, Hungarian sausage, beans or veggies, Mexican beef etc.) and then topped with one of seven sauces - you will not walk away hungry. Quite frankly, we have no preferences to fillings here and we’d happily eat them all! The venue itself is cosy enough, has a warm brass bar, plenty of Danzig-era signs and paintings on the wall. Check out their cellar bar below called Jopengasse, which stocks a range of craft beers and is named after the name of this street in German, which itself was named after the most famous of the beers brewed by Johannes Hevelius when he wasn't looking up at the stars.
