Mleczarnia Jerozolimske is located in the small strip mall located next to the Intercontinental Warsaw.
We were walking around exploring the area after checking in. Although this looks like a no frills place, it was fairly crowded and people were coming in and out with regularity so we decided to try it out.

The chicken plate came with a leg and thigh, two scoops of mashed potatoes. The chicken was well cooked, and was fairly moist, but could have used a little more salt. The dish also came with a thin chicken type soup, and a watered down type of juice. I am not sure if the soup and juice are normally served on the weaker side.

The roast pork was topped with a thin gravy, and also came with mashed potatoes, soup, and juice. The pork was tender and pretty flavorful, and the portion was generous considering the price.

The pierogis came 7 to an order and were topped with caramelized onions. The dough was chewy, but not too thick. The onions added a little sweetness to the dish.

The restaurant also has a self-serve salad of beets and onions, which was very flavorful.
If I remember correctly, the whole meal was under $10. The food is not gourmet by any means, but it was a filling meal and very close to the hotel.
