El Farolito in L'Hospitalet is an amazing spot for authentic local food
I went with two others and had a fantastic experience. The service was excellent, and they offer plenty of gluten-free options. We tried the seafood paella, Bacalau a la Llanuna (a deliciously large piece of oven-baked cod), salad, and dessert—all were perfectly prepared and full of flavor.
They also have a spacious outdoor patio. Highly recommend this place for great food, service, and ambiance. Go there. Eat there. LOVE IT THERE!
