The restaurant’s atmosphere is casual and inviting, ideal for both quick bites and relaxed gatherings, targeting anyone looking for fresh, boldly flavored seafood in an unpretentious setting.

The menu highlights instantly showcase its strengths: standout dishes like Fish Tacos, Grilled Shrimp Tacos, and the flavorful Cóctel de Camarón deliver a true taste of coastal Baja. The complementary consomé, a shrimp-based broth served upon arrival, sets the tone with a warm, comforting invitation. Other crowd favorites include the Tostada de Aguachile Verde and the signature Carne Asada Nachos, which balance surf and turf in vibrant, hearty combinations.

On the flip side, a few reviews mention a credit card surcharge that isn't always communicated upfront, which may catch some diners by surprise.

This is my 3rd or 4th time here. Excellent food! Love the food and the atmosphere. They give you a small complimentary shrimp soup and it is delicious. My issue is it takes a looooong time to get your food. Which isn't a deal breaker but it is inconvenient. My second issue is they charge a $0.75 fee I'm assuming on credit card transactions. I was not told there would be a 75 cent charge, nor was it explained. Now the 75 cent would not have done anything to our visit, order, or perception of the restaurant. However it would be nice to know about it. Still one of the best tacos we have had and we will be back for more. Edit: Stopped by here while visiting family and the prices have skyrocketed and they still charge $1 for the credit card fee and they didn't mention it. Lowered my rating to three starts and the prices seem excessive and the fee not being mentioned. Only restaurant I've been to that charges a fee for using a credit card.

I used to really enjoy Mariscos La Baja, but the food just isn’t as good as it was a couple of years ago. Not sure what changed, but the flavor and quality don’t seem as fresh or bold anymore. Prices have stayed about the same, which is good, but the overall value doesn’t feel as strong when the food isn’t quite hitting like it used to. Service is still friendly and the place is clean, so it’s not a bad spot—just not as impressive as it once was.

One of my coworkers put me on to this place. Amazing food, I love their fish tacos, their consome and the chipotle sauce. Absolutely cannot beat the fish tacos here. The ceviche tostada is really nice as well. I’ve tried the adobada taco as well which is good. I also like how they give a good amount of limes to eat with the tacos. Also I always wash the food down with horchata.

We have ordered from MLB for takeout on numerous occasions. The fish tacos are tasty. The octopus-shrimp cocktail, beef-shrimp quesadilla, the guero loco and tostadas loco are all fantastic. Unbeatable price for top quality fresh seafood! Dine-in experience is even better. Best Mexican food all around!
