Petra is one of the busiest tapas restaurants in El Born that’s super popular amongst both locals and travellers. Most probably due to its central position and overall epic culinary experience it offers. The food is amazing, with an option for both seafood and meat. I always go for their burrata with tomato, which is simply amazing. You’ll most likely be made to wait, so if you fancy getting seated fast and are not up for standing around I’d recommend making a reservation.
