Favorite restaraunts in Barcelona and Seville?

Food in Barcelona is so good! There are books, where you can see the best restaurants or street food. Maybe buy one of that to have a good overview

I spent a week in Seville last month and had breakfast every day at this place. Super authentic, and crowded with locals. Not sure it's worth going out of one's way, but it was on my walk from the AirBnB towards the center. Also had a great dinner at Perro Viejo. Kind of nouveau/trendy/stylish, but the food was great and the scene was local.

Devour Tours are well regarded for their food tours in Spain. And one of the founders has a YouTube in which he talks a lot about food and restaurants in different towns—find it under Spain Revealed.

This place has bull heads on the wall as well! If we had gone here on our first night in Seville instead of the last, we would have eaten here every night.
