"Have you ever had a situation where you wanted to whip out your phone and post a 5 star review immediately upon finishing your meal? This was the case the first time I ate the '7 Chiles Taco ' at the Mariscos German food truck in its permanent residence in a liquor store parking lot on Beyer Boulevard in south San Diego. This game changing taco has large chunks of moist, mild flavored grilled fish in a delectable sauce confirmed by Chef Jorge Fuentes to contain blended fresh jalapeño, fresh habanero, fresh güerito, fresh serrano, árbol, guajillo, and chiltepin (aka the 'mother of all peppers ' , oregano, and chicken bouillon. Drizzled over the fish and two giant slices of fresh avocado. Crispy leaves. Double corn tortillas. The resulting taco is spicy, juicy, crunchy, and perfect. If you somehow don 't remember to order that one, give their O.G. 'Taco de Pescado ' (Fish Taco a try. There is a slight sweetness to the batter they use to fry the fish here, it is almost like a funnel cake and details like the sweetness of the batter matters in a city where nearly everybody has figured out how to make fish tacos really, really well. The difference between the best and everyone else often comes down to small deviations and subtle secrets. The tempura like batter is otherwise similar to most others, perhaps a good deal crispier. The white sauce is nothing special, the packaged tortillas are inoffensive, and the fish is sufficiently moist, but it is the peculiar taste of the batter that keeps me coming back here and ordering their Fish Taco. The 'Gobernador Taco ' features stir fried shrimp, tomatoes, bell peppers, onions, and... celery, with melted cheese. Cajun cooks refer to the combination of peppers, onions, and celery as the 'Holy Trinity, ' as it is at the base of most Cajun stews and gumbos, similar to how the French use mirepoix or Mexican cooks use sofrito. I couldn 't help but think 'shrimp étouffée ' while eating this taco. The combination of these elements results in a savory, sweet, greasy, and gooey taco that just flat out works. As excellent as the tacos are, my favorite thing to order at Mariscos German Beyer is the 'Tostada Loca, ' a massive plate of seafood served with the aforementioned '7 chiles sauce ' along with tostadas fried on premises on a daily basis. This plate of food begins with a layer of white fish ceviche with tomatoes, cucumbers, cilantro, and onions, topped with another ceviche of cooked shrimp with more tomatoes and cilantro, then a layer of poached octopus, boiled whole shrimp, scallops, de shelled white clams, then garnished with avocado wedges, sliced red onions, and raw shellfish: chopped mussels, whole oysters, and black clams in their shells. The entire thing is then doused with a combination of Maggi and freshly squeezed lemon juice. The 'Tostada Loca ' is our modern tower of Babel, a sign that man has mastered his universe, and a symbol of self idolatry in defiance of God 's will. Back to that eye opening first visit to Mariscos German Beyer: I had been behind a family of 6 on a Sunday afternoon with their thick southern accents, obviously tourists, but smart tourists who had enough sense to know THIS was the place to order 20 different tacos... and I said to myself, 'oh boy here we go, I 'm gonna be here for an hour behind these people, ' but the man taking the order cut through the chaos with great efficiency. Further, their order was served to them in less than 5 minutes after they put it in, and mine served to me just a minute after that. More evidence that quality pervades every aspect of this inexpensive lonchera."
