I made a special trip to exit 25 to try *The* Taco Truck and was greeted by a very nice couple and simple menu. Don't be intimidated if you don't speak Spanish, they are bilingual (he more than she) and have the menu broken down to make ordering easier for those who were not lucky enough to be raised in the heart of good Mexican food. For today I can only rate the Taco de Carne Asada.
I would say the tacos are a 3.5, maaaybe 4 stars. The carne asada was tender w/crisp edges, very little fat. Loved the lime, grilled onion and healthy dose of cilantro. I think what woulda made this a solid 4, for me, woulda been a light drizzle of fresh creme. The salsas are rockin' but not for those w/a wimpy tongue. As it stands, I still prefer the tacos at Burrito Loco but these are also quite good.
Tip: get extra grilled onions; they are sweet and your taste buds & tummy will thank you!
