I found this restaurant by chance, but it's one of my favorites, the site is very special with inviting decor and fabulous food as great prices. I ate some nachos which were delicious (€ 2.50) and a huge hamburger that I couldn't finish with fries and everything (€ 3.75), but they also offer grilled food, salads, pasta, risotto, pierogi, etc. It's highly recommended with special food, location, all - I recommend it.
Surprise restaurant in the center of Krakow that we discovered it by accident as it is hard to find. It's in a basement and in a small shopping arcade on a street near the square. The place is charmingly decorated with very soft jazz music, curious that bird music is in the bathrooms. We tries several things and everything was good, especially the spaghettis which were a delicacy. Fine food, service and the price was better yet, just 10 €/person. Highly recommended.
