Federico's is a very small, take-out place. There are many options for fish tacos in Kauai, but these were some of the best I had while visiting. Fresh corn tortillas, plenty of grilled, fresh fish and avocado. Served with beans and rice. All were good. A plus was the guitar player on the patio. Good musician, pleasant night air and some good eats. They don't serve beer or liquor, but the General Store is in the parking lot and you can buy something there or at Foodland, if you like to have a beer with you Mex food. Reasonable prices too (for Kauai).
