I've been driving home past a taco truck on 1st Avenue just before it turns into Lakeshore (btwn 14th and 13th, I think)...It's on the right-hand side of the street where a cheesey used car place used to be.
We got a tongue taco and a "spicy pork" taco and a burrito. The burrito was just so-so - sort of dry and bland, but the tacos were fab. The guy also put a little packet of pickled carrots, chilis, etc. in the bag.
Anybody else been there? I was impressed.
