Late Night Taco Truck in Madison, Wi. They are open Friday, Saturday, and Sunday 7p-3a. Absolutely best tacos and quesadillas. They park on Regent St near MPM and the Red Zone. I love the Chorizo there. Definitely give it a try if you are near down town on the weekend. #madison #madisonwi #madcity #taco #tacotruck #food #delicious
