Had to update: came to this location again, and the fish taco is also very amazing! Definitely my favorite mariscos spot in San Diego! This place is so good! I got a shrimp cocktail and it was amazing! Didn’t even need to add anything to it, it was perfect as is! 10/10 would recommend!

Really good food! Ordered some fish tacos, a seafood burrito, and a blue fin ahi tostado that had jalapeños. I really want to go back and check out the rest of the menus — there is a pretty decent sized variety that looks good. The service was typical but everyone seemed nice and friendly. I couldn’t really hear the person taking my order because they were cooking and frying and the exhaust fans were going on —- but the person was nice enough to repeat themselves. I’d definitely come back and order food again.

If you really want to feel like you're in the streets of Mexico, come here. The overpowering smell of Fabuloso, the blast of loud Mexican music, and oh my God the flies. . . The cocteles are good, though, but expensive. $20 for a 16-ounce shrimp cocktail. . . My friend and I got a cocktail, a plain quesadilla, and a fish taco and two cans of Coke and it was $45. The proprietors are nice, and it's good that they give the little cup of consome

I stopped by this food truck with attached, covered patio. The proprietor was welcoming, very knowledgeable, and patient with this newcomer from the neighborhood. It was a cool, damp, and rainy Saturday morning, so a complementary cup of hot broth warmed the tongue while waiting to be served. I ordered 2 tacos with everything, but mayo, to go. I added guacamole condiments and napkins. When home, those two fish tacos were so good that I wished for another one! Sometimes, there's a great eatery only a few blocks away from home! YAY!

The food was fresh, really good and the portions were good size. At first I thought the large shrimp cocktail looked small and wasn’t gonna be enough but it was plenty, I ended up getting a jumbo mixed seafood cocktail that was really jumbo and it had a lot of good shrimp, oysters, scallops and octopus and I couldn’t finish it. The gobernador was really good also. The place is worth a shot for sure
