We arrived to this restaurant based on the reviews on tripadvisor. We received a very warm welcome by an amazingly friendly stuff. The place is located off the main tourist attractions and I guess that's the reason that it's not so crowded. The food was excellent! fresh mussels, with excellent sauce. The Paella was one of the best dishes I've ever had with well cooked rice and lots and lots of seafood. Even the dessert - Catalan cream - was wonderful. And I booked online and received a 30% discount! so for a very full meal for two - which my Significant other failed to finish - we paid 40 euros, which is a real value for many.
Overall - Excellent food, nice and authentic Catalan atmosphere, very friendly and welcoming stuff. I would definitely recommend it! very worthwhile to take the time and visit this place if you're in Barcelona. Cheers
