What you’re about to see is way beyond coolness. It’s a PRL design aficionado’s paradise and just the perfect spot if you want to grab an iced coffee and chill in the shade for a bit. In front of you there’s parked cars and a road, but beyond that there’s the very big Park Skaryszewski (aka Skaryszewiak or Skaryszew) so you’re looking at trees the whole time after all.
It’s Vintage Kolektyw Kawiarnia & Sklep in Washington Alley (Aleja Waszyngtona) 30/32, Warsaw.
Their coffee is delicious, just the right hue of sweetness (not the sour one), and they do a decent iced matcha latte if you want it, too (sweet or not sweet, up to you). They also sell traditional blok czekoladowy (sth very much like tiffin) and lemonade.
I’ve tried their hot and cold drinks and bought myself a glass collectioner’s notebook (Notes Kolekcjonera: Szkło). I don’t collect chairs or glass or lamps or clocks, but finding vintage glass is the likeliest (like I once did with awesome PRL tableware that I found when throwing out glass rubbish).
