Tacos Revolucion in Bonita is the best carne asada I have had yet. I have been eating here for 6+ months and it is consistent. Always a great sear, you can see the grill through the window in the bar seating. The pollo asada and pork adobado is also excellent. They have the salsa bar with radish, marinated onions and grilled peppers, awesome hot sauces but most importantly incredible peanut hot sauce! If you are in the area you have to try it.
It seems to be expanding so hopefully central and northern SD will get a location too.
