I work near this place and everyday I'm tempted to not pack a lunch! I've tried lots of taco places and this place is certainly #1. I highly recommend: gobernador and blackened mahi mahi! Those are my favourites :)
They also have baha (good classic), octopus (for the adventurous! It's good!), marlin (for those who like a dense fish!), carnitas (another classic) and the catch of the day (which is always an interesting surprise)
If you're going for lunch, be sure to get there early! The line gets long!
