The best place we ate at during our trip to PR. It is in the Luquillo kiosks. Forget the number. Place was recommended by several of my husband's coworkers. Top shelf drinks handmade to perfection at a low price. Can't beat that. The food was also very good -- loved the nachos. I bet anything you order will be just delicious! Exceptional customer service. Ate out every day going to new places but kept wanting to go back to the Burger Shack. Would recommend to anyone staying in Luquillo.
