What People's Say About Place

I travel all over the US for work, and am a restaurant snob. I will typically only eat at a place if it is rated 4.5 or above. I will tell you that this place should be rated 5 stars. It has something you don’t find much these days…..charm. The food is excellent, but the owners are what makes it special. I recommend the molcajete.

Customer service was great. I got the carne asada fries which comes with a free soda, it was good. It was big enough for me to share with my child. Every time I've gone here I've always order the same thing. It's a good place for a quick bite.

Very friendly. Lady here is a sweetheart. Had a Campechana and though the ingredients differ from my own recipe, it was still great. The shrimp were nice size and the cilantro, onions, pepino...all tasted crisp and fresh. I will be back to try other items from the menu. The fresh fried tortilla chips were warm and delicious...and their salsa is 8 out of 10 for flavor, with just the perfect amount of spice. Hope to be working in the area again soon.

Today we biked from Coronado Island to Downtown San Diego, and along the way it was time for lunch. We found this little hidden gem. The food and the service were great.

I had a lovely experience in Costa Azul Mariscos. I ordered the mixed combination which had a lovely variety of fresh shrimp, octopus, fish and other vegetables with an amazing flavor and good agua de horchata. They also serve warm and crispy chips and salsa. The gentleman preparing the food was very polite, hospitable and made sure everything was to my tasting and comfort, I highly recommend this establishment for some good seafood.

This place is a hidden gem. I've been coming here for 20 years and the food is fantastic. It's flavorful and very well cooked. The service here is amazing as well; they treat you like family and gives you a homey feel. There's no other place in San Diego that serves authentic and fresh Mexican food and seafood like Costa Azul Mariscos. I recommend this place to anyone who comes around Imperial Beach!

Wife and I ordered the chicken quesadilla and a couple beers while waiting for our car to be fixed at the jiffy lube across the street. We were super surprised at how good it was! Great flavor and about $15/20 total. Food was $13 and $2/3 for each beer.

Nicest people ever! They have weekly deals too! Super yummy fish tacos, recommend.
