Located at 1620 W Foothill Blvd in Upland, CA, Senor Baja stands out as a fantastic Mexican eatery, particularly renowned for their drive-thru service. Customers rave about the freshness of the food, enhancing the experience despite a slightly longer wait time. Eric Tucker emphasizes this, praising the seafood cocktail with shrimp and octopus—a true stand-out dish that showcases the restaurant's commitment to quality ingredients.

The star of the show, however, may very well be the fish tacos. Dan Rhinehart can’t help but express his enthusiasm, stating they are the "best fish tacos" he has ever tasted. This sentiment is echoed by many, marking them as a must-try for first-time visitors. The vibe of the restaurant is warm and inviting, as noted by Ernest Castillo, who felt right at home with attentive service reminiscent of a family dinner. His recommendation to pair the shrimp burrito with chipotle salsa adds an extra layer of flavor to this already delicious dish.

While some patrons note possible inconsistencies in operating hours, the rave reviews of both the shrimp and the fish tacos make Senor Baja a culinary gem worth visiting. With a commitment to fresh ingredients and a welcoming atmosphere, your taste buds will thank you!

This is probably the best drive-thru Mexican food around. Be patient, they make the food FRESH! It's worth the wait! Be sure to try the seafood cocktail with shrimp and octopus!

The Fish tacos are out of this world! I don't think I have ever had fish tacos as good as these. I'm sorry I can only give them 5 stars. I would like to give them 10 stars in a review.

So I came in for a shrimp burrito because they’re so good, the lady was really nice, and she brought out the food with salsa and set on the table like if I was at home with my grandma, I asked if she had red salsa because the salsa I got was a lil too sour she said no then after a min she said we have some red chipotle that’s hotter if you want that I took her upon that offer it was so good spicy too but delicious! Pull grab a shrimp burrito and ask for some chipotle salsa on the side it’s worth it!

Not sure what time they open but the food is great! There are no times posted out front and I’ve been sitting in my car since 8:19 am. Still no one here

Wow! I stopped here looking for lunch and wanted an easy meal. The drivethru made me think it'd be mediocre fast food. It was not. I ordered the chiptole mahi mahi fish tacos and it was delicious. There was a bit of a wait, but that's because they made it right there instead of premade heatlamps. Will definitely be back to try more of the menu!

The grilled fish burrito was amazing! The service was great! I would definitely recommend this one. There are only 4 or 5 locations. Worth the drive.
