Mariscos Playa Hermosa is kind of in the, shall we say, less savory area of town, but don't let that deter you from trying it out! The outside pretty much looks like a crummy box but the inside is super colorful and lavishly decorated. I wasn't sure what to expect but the food sufficiently impressed me.
You get two salsas with a basket of chips--both of which are super delicious. The avocado salsa was tasty and not super watered-down like at some places. The red one, which is semi-spicy, is very tasty. I don't even know how to describe it. It was just so.... TASTY.
We received some salmon (I think?) ceviche on a crispy tortilla with our meals. Very yummy and the veggies in it tasted fresh. I ordered the enchiladas de jaiba and the others ordered fish tacos. Both were good although I think I liked the fish tacos better than my enchiladas. I thought the fish was really good and light. I noticed the rice seemed to be made with those frozen mixed veggies you get at the supermarket, which I thought was kind of funny, but it still tasted good so I guess it didn't matter.
Service was very prompt even though the server wasn't particularly engaging. I actually prefer my service to be this way, so if you prefer a waiter/waitress that likes to make conversation, then maybe this isn't the place for you. Interior of the restaurant looked relatively clean.
I definitely recommend Mariscos Playa Hermosa. Don't be scared of the rundown appearance of the area! I cannot speak on the authenticity of the food but at least it was yummy.
