Closed for renovations. Serious competition for Niezły Dym, Piec na Szewskiej makes some truly mean Neapolitan pizza, vouched for by the endless stream of patrons vying for a table. The decor is nothing much, the service is hit or miss, but no one comes here for that - the great selection of authentic napoletana, made with DOP San Marzano tomatoes and ingredients like pecorino cheese, aubergine, prosciutto di Parma, and mozzarella di bufala, is more than sufficient to outweigh the flaws.
