The Guaco Loco is a hard taco resting in guacamole inside a soft taco shell. They have options of ground beef, fish (chunks, fried) or chicken (my favorite - is shredded). I have been eating the Chicken Guaco Loco with hot sauce and jalapenos (they are pickled not fresh) at this place for more than a decade and I never miss it when I'm on South Beach. They have bottled Mexican beers to accompany (not a full liquor bar). This is a still-have-sand-on-your-flip-flops kind of place so if you want to be served you should go somewhere else, but then you'll have to rinse your feet off.
