This place is a must-go if you like to enjoy a good cup o tea, interesting conversations with the owners (who speak French, English, Polish and many other languages :)) and if you are into contemporary art. Every Saturday Happy Day opens its doors for anyone (for free!) to meet a new artist: painter, photographer, sculptor... You can enjoy an exhibition, while sipping delicious tea. Every artist is different, so you can get to know what's popular these days among amateur, as well as professional, artists in the heart of Europe. This place is hidden in the small cozy street which makes it even more authentic and special :)
