We have been to this Mercato in a few occasions and I can say with confidence it has nothing special. The biggest advantage, for my view, is the weekdays lunch special. It offers an appetizer and entry for a low price ~25zl. Portions and service is ok. Apart from it, food is basic, no sides, no bread, no complementary anything. We have to paid extra for a piece of baguette to accompany our tomato soup. Flavor is quite average, or below average when compared to other Italian restaurants in Warsaw. Wine assortment is good but expensive. I was able to find better choices in the winery store right across the street. Services is ok, but once again nothing great. They take good 20 min to bring your food and when served you may encounter disappointment. In our opinion, this area has so many other great options… :O
