Finally tried the new truck on Roosevelt Ave. in Woodside last night - and I think I found my favorite tacos! I had lengua and tried some of my BF's chorizo and al pastor. My lengua was as I like - tortillas perfectly toasted (not on a grease), meats perfectly seasoned and grilled with just enough burnt ends, topped with chopped onions and cilantro. For the self-serve toppings, besides regular marinated jalapenos from a jar, they also had (homemade?) jalapenos roasted with onions - yum! Have not tried their salsas, as the tacos were so delish I felt no need for sauces. Highly recommend.
Besides tacos, they offer huarraches and tortas. Small operation, very small truck, few meat toppings - but very good.
The truck is parked on Roosevelt late nights in front of 99 cent store between 63rd and 64th everyday except for Tuesday IIRC (will ask again).
