If you love meat, check out these two restaurants. They were recommended to me by a Barcelona steak lover.
1.Cal Boter (Catalan restaurant)
Tordera, 62, Barcelona 08012, Spain
For meat, I recommend you “Cebot 500grm”. You can eat it or share between two.
Usually you should call to make a reservation.
2. Nervión (Vasc restaurant)
For meat, I recomment you “Chuleton”. It is very big and you should share it.
For the best Patatas Bravas I can whole heartedly recommend, Bar Tomas in Sarrià - they are amazing!
Enjoy your trip!
All the best,
