I walked in and was greeted by the friendly lady behind the counter who speaks both English and…read moreSpanish. I walked in at 9:00am and I ordered 2 bacon, egg, cheese and papas ranchero tacos. They were probably fairly portioned but I wouldn't say they were overstuffed or anything. I got them on flour tortillas, which were, in themselves just OK in my opinion. Overall though, the tacos were tasty and hit the spot. The jalapeños in the papas rancheros added a nice spice level for me but I love my food to make me sweat so if you don't prefer higher spice levels, just get the regular potatoes. As for ambiance, this is a taco counter with an open kitchen and a flat top grill inside a gas station (inside the Valero on Chris Kelley Blvd by the KFC) so I got what I feel most would've expected there. All in all it was a pretty good hot and quick breakfast and I'm sure I'll be dining with them again since I have an office pretty close by.

They do have a few tables with a canopy set up in front of their truck if you wanted to eat there. We ordered the Trio which came with one birria taco, one quesadilla and one flauta along with consommé. When I saw how red the taco shell was, I knew immediately this was going to be a hit. I absolutely love how they don't skimp out on the birria and really pack it in so you're indulging in pure bliss with every bite. It's been awhile since I came across a food truck that served birria ramen so I definitely will be ordering that next time.

This was so cheesy and grate…read more Highlights: * Birria * Aguas Frescas * Dessert Empanadas Review: The only thing cheesy about this spot is their quesa birria options. Their quesa birria tacos were cheesy packed with beef birria and serve with a side of hot consome. Their flautas were the real deal fried, crunchy, flavorful and again super cheesy. Their birria egg rolls were next level with a super crunchy exterior that is a perfect bite once you dip it in the consome. The highlight of the day was the agua fresca super refreshing which had the pineapple and mango mixed to create this amazing fusion that was elevated by the sweet tartness of the chamoy and tajin. I can't wait to go back for their other birria options and aguas frescas. Great service and chill ambiance.

Of the tacos I tried, Al pastor was by far the best. They're the street taco variety, so palm sized but packed with flavor. Beef and chicken were both tender and moist but didn't have the same flavor punch. Toppings are serve yourself and they got the usual (onions, cilantro, salsa). Will say that salsa packs a kick, whether it's green or red. All in all highly recommend!

The barbacoa meat was super flavorful and the portion was good. The al pastor was surprisingly really good too. It had pineapple in it which was intimidating but the flavor contrast was so good. The chicken and steak fajita tacos were not my favorite. It was kind of flavorless and the meat tasted a little off to me. The tacos paired well with the light green sauce as it added a nice creamy taste. I also enjoyed the papaya agua fresca as it was so refreshing and not too sweet!
