Umberto’s move from Poznan’s busy café quarter to this quieter spot inside a former telecommunications bunker in Citadel Park was a genius one. The location is a relaxing oasis surrounded by an elaborate garden, drawing in Citadel visitors refuelling on simple salads and an extensive list of pizzas. A small window allows folks on the move to buy drinks, snacks and ice cream quickly as well. But we advise you to grab a seat and enjoy one of their trattoria’s staples, especially since a large playground abuts the restaurant, making Umberto an ideal spot for families using the park (there’s even water dishes available for pets).
