Dress codes are usually written as a list of prohibitions, which tells you what will get you turned away and nothing at all about what to actually wear. Smart is the standard here, and in practice that is a wide and forgiving category.
What follows is the useful version: what works in this particular room, and the two practical considerations - cobblestones and Polish weather - that catch visitors out more often than the dress code itself.
What Works Here
A dress, a smart jumpsuit, or tailored trousers with a good top all sit comfortably within the code. The room is dark, warm-lit and built from white leather, black velvet and gold, which flatters most things and particularly rewards anything with a bit of shine or structure.
There is no expectation of formality. Something you would wear to a good dinner is exactly right, and most guests treat the evening as a reason to make an effort rather than a hurdle to clear.
The Cobblestone Problem
This is the genuinely useful part. Krakow's Old Town is paved with cobblestones and setts, and they are unforgiving to a narrow heel. Every visitor discovers this, usually about forty metres from the taxi.
A block heel, a wedge or a good flat is the practical answer. If you want the stiletto, factor in that the walk from the edge of the pedestrian zone to our door is on stone.
Weather and the Cloakroom
Krakow winters are cold and the venue is below street level, which means you will arrive in a coat and immediately want to be rid of it. There is a cloakroom, so dress for the room rather than the street.
In summer the cellar stays comfortably cool thanks to the stone vaults, so a light layer is worth having even in August.
Frequently asked questions
What is not allowed?
Sportswear, tracksuits, trainers, shorts and beachwear. Beyond that the code is smart rather than formal, and most outfits you would wear to a good dinner will be fine.
Do I need to wear heels?
Not at all. A smart flat is entirely acceptable and considerably more practical on Krakow's cobblestones. There is no requirement about heel height.
Are trainers really refused?
Yes, including smart or designer trainers. It is the most common reason guests are turned away, so it is worth taking seriously.
Is there a cloakroom for coats?
Yes. The venue is below street level and warm, so you will want to leave a winter coat at the door rather than carry it around.
Is it cold in the cellar in summer?
It stays comfortably cool because the stone vaults hold a steady temperature. A light layer is worth having even in August.
