The food was healthy and tasty, the service was good, and the atmosphere is great! The dishes are by no means authentic (whatever they claim to be), but have good flavors, and you feel like you're getting a few nutrients, which is an anomaly in Iquique restaurants!
The hostel is just across the street from the beach, and 5 blocks from a supermarket. Has a great kitchen, small bar, tv room, and amazing views from its rooftop. Highly recommended if you go to the beach-fresh juice from the giant pineapple.
