We found this little market on the map when we were staying nearby, it's not very well advertised, definitely a hidden gem of Warsaw. You can only access it via an unnamed road off of Ulica Towarowa, right past the rail museum and post office. Don't be deceived by often-wrong google street view.
Excellent place, lots of food trucks with food from around the world, Vietnam to Brazil and lots in between. They had a dj playing music when we were there, nothing crazy or too loud. They open in the afternoon and go into the evening. Whatever you're in the mood for you will find it here. Lots of beer, wine, and hard alcohol stands as well. There are plenty tables and chairs to sit at. You can carry your beverages and food anywhere you want. The vendors give reusable containers for a returnable fee, just bring back watever token they give you, and you'll get the deposit back in whatever form of payment you used.
I rarely give 5 stars but this one is well deserved, whomever organized this did an excellent job. Whatever food/drink you're in the mood for you can find here and it's very good.
