Studio Qulinarne offers truly excellent modern European fusion cuisine that could be easily compared to restaurants in Paris, etc. However, it is at a fraction of the price as Parisian etc. restaurants of the same quality.
I've eaten twice at Studio Qulinarne, and served both times by the same waiter. The waiter really knows his food and drinks; he is clearly very knowledgable and speaks English and Polish well. However, the first time we went, he forgot drinks, and the second time we went, he brought me the wrong drink and billed me for it anyway (along with the drink that I actually ordered). To me, that's totally unacceptable.
However, the food and drinks are really top-notch... especially the Carbonara (best in town to my taste along with Makaroniarnia and Del Papa), the Caesar (the only good one I found in Krakow in a year living there), and the Cocktails are truly awesome.
Can you suffer an arrogant waiter who makes lots of mistakes for the sake of truly great food? I can.
