Taqueria El ARBOLITO is a straightforward Mexican restaurant tucked into a cozy spot on E 4th Street in Ontario. It’s the kind of no-frills eatery where locals come for authentic, well-prepared tacos and tortas that showcase tender, carefully cooked meats with real attention to flavor. The compact space fills quickly, hinting at its steady local popularity, so expect a casual, bustling atmosphere rather than a spacious dining room experience.

The menu highlights stand out for anyone who enjoys classic Mexican street-style eats. Favorites like the carne asada lengua and tripas tacos, chorizo mulita, and well-balanced burritos bring variety with traditional touches. Dishes come with fresh salsas, and simple sides like radish, lime, and sautéed onions with jalapeños add to the authentic feel. Those interested in breakfast-style options will appreciate the huevos rancheros and chorizo con huevo plates served with warm corn tortillas.

Service at El ARBOLITO tends to be warm and personal — a common experience among customers who notice the friendly staff’s willingness to accommodate and help, even when orders need adjusting. The team’s genuine approach fits the intimate size of the place, making it a welcoming spot whether you’re popping in for a quick lunch or sitting down for a relaxed meal.

This taqueria is best suited for people who appreciate authentic Mexican flavors without the distractions of a large or trendy setting. It’s ideal for locals craving quality tacos, burritos, or tortas with well-sourced meats and fresh ingredients. The lunchtime and early evening hours see a steady flow of regulars, making those times excellent for visiting if you want to catch the lively, energetic vibe.

This place is the best in the I.E. to have authentic Mexican tacos or torts. The meat is tender, and I found no chunks of fat at all. They use really good meat for the asada and the tripa tacos are delicious . The only thing I didn't like is that the place is too small, they could use a bigger establishment.

I wanted to take a moment to highlight the incredible customer service I received from Carmen. She was not only kind but also exceptionally generous, especially when I mistakenly placed the wrong order. Without any hesitation, she happily changed my order and reassured me with a warm, "It’s okay, mija, no hay un problema." This level of care truly embodies what great customer service should be. I also want to mention how kind Carlos, who was making my tacos, was during my visit. I am so grateful for their thoughtful approach and positive attitudes. I highly recommend this place, and I sincerely hope the manager acknowledges the outstanding service provided by Carmen and Carlos. Thank you both for making my experience a wonderful one!

I discovered this gem of a taco spot during one of my clinical rotations, and I’ve been hooked ever since! The tacos are hands down some of the best I’ve ever had—fresh, flavorful, and perfectly seasoned. Whether you're grabbing a quick bite or sitting down for a casual meal, this place delivers every time. Highly recommend stopping by if you're in the area—you won’t be disappointed!

I can not express how GREAT their green slasa is. I would have to say its one of my top 3 favorite salsa. The burrito was good as well. You add the green salsa and forget about. Every other burrito is lame. The restaurant itself is small and not the prettiest. I have a Dodge Ram, it didn't fit in the parking spots. I had to park in the street. The area feels kind of sketchy when you go there at night times.
