This unsuspecting taco truck may appear plain but hold on to your tastebuds because the flavors will explode. Simple menu but they make their food very well. I love the "cabeza" as my meat in their tacos. It takes like a prime rib with the flavorful fat attached to it. The portion of the meat is ok, it could be more, but you could pay for extra meat. The food truck is parked by the Grocery Outlet parking lot, it seems sketchy but just go during the day if you're not comfortable being at the area. The speed of their service is good and friendly people. They take cards which helps people who don't carry cash.

The birria is sooo good! Cash only :) sketchy spot but makes it more fun for people watching! My boyfriend and I come here and then we eat the food in his truck while people watching ;) fun date haha. I would come back again!

I've been craving a good home-made burrito that was not dry and this food truck hit the spot! I ordered a Super Burrito and in all honestly it was one of the best in Vallejo. Yumm!!

I Love this food truck!nice people, great chef Fair prices. It's a must when you're in Vallejo

When in town visiting family, Tacos Mexico is a must! I have to go at least once! I love the burritos at this taco truck spot and have been coming here for years! I usually order their Super Burritos which are filled with whatever meat you want with rice, beans, sour cream, cheese, onions, and cilantro. With your burrito, they also give you a side of tortilla chips. Their burritos are large in size. My go-to meats in my burritos are usually carne asada or carnitas. The meats are usually flavored well with their seasonings and everything in the burrito just goes well with each other. The burritos are large enough that I can have it as two meals. Tacos Mexico is located near the Grocery Outlet, which used to be the old Yard Birds lot. There are always plenty of people but they work quickly! Make sure you have cash as they only take cash. No cards!

So I'm obsessed with their burritos ! I'm eaten so many different burritos from other burrito trucks, and restaurants, but these are the freaking best! I love the Carna Asda burrito with extra rice no beans and the Birria (Goat meat) burrito with extra rice no beans! The folks are friendly and super chill, be sure to bring cash, because they don't take card. It's a grab and go atmosphere, or you can sit in our car and chow down on your food! 10/10 5 stars

Had their birria tacos! Amazing! this might be my go to stop from here on out! Cash only I believe

***3.5 Stars*** The carne asada tacos go crazy. Mm mm mmm, soooo bomb. That's where it's at. Authentic tasting street tacos that will have you sweating up a storm if you like 'em hawt n' spicy. It's that "slightly hoodish so you know it's goodish" kinda vibe. Hit up this truck with a friend not too long ago, and the carne asada tacos really impressed. The carnitas burrito and tacos were average, but I would still come back for those carne asada tacos alone. This truck is located right off of the freeway (Admiral Callaghan) in the Grocery Outlet parking lot. It's definitely a popular truck and people were waiting in line to order (not a super long line, but they do have some fans). I ordered 3 carne asada and 2 carnitas tacos, and my friend ordered a carnitas burrito. The tacos are cheap at $1.50 a piece ($2.00 for asada, lengua, and tripa) and it's cash only. They'll ask you if you want mild or hot salsa. I made the mistake of getting all hot salsa because I have a higher tolerance for hot and spicy foods. Well, at least I THOUGHT I did. Sh*t was so hawt that beads of sweat started forming on my forehead as I was eating these suckas on the couch! Like haaaawt! Now don't get me wrong... it was delicious! BUT... if you can't take the heat, don't do it. The carne asada tacos were dynamite. The meat was spiced up so nicely. It was nice and tender too. The only thing that I found weird was that they put lettuce on their street tacos. Hmm... never seen that before. But for some reason, it was oddly refreshing and I liked it. You can always ask them to prepare it without the lettuce, but I just left it as is since this was my first time at this truck. The carnitas tacos were decent but the meat wasn't as flavorful as the asada. Plus, I like my carnitas really crispy and this consistency was more like a broiled style. Not my favorite. My friend wasn't a huge fan of the carnitas burrito either. I tried some of it and I thought it was just okay. It actually didn't seem to have much meat in there. It was a nice size though. One thing I'll mention is that there were some sketch characters hanging around that parking lot. This isn't the fault of the truck, but just be mindful. They were pretty quick with our order, so luckily we weren't waiting there for too long. All in all, it's a solid spot for street tacos. I would definitely come back for more of those asada tacos.
