We are at this place on Friday night, and overall we were impressed.
The service was excellent - attentive and professional without being overbearing.
My food was nice - I had scallops for starter and beef for main and they were both cooked very nicely. My wife's starter of salmon was a bit average but the main of pork was exceptional.
The only drawback was a limited wine menu, but that seems to be the case in many restaurants in Krakow.
Definitely worth a visit.
