Koku Kitchen Buns1
Why locals love it
It's an underground place with some of the best ramen of the city. If this doesn't convince you to go, one of the owner is also irish, so it has this mouthwatering banoffee in its desserts menu. Also, the selections of dumplings is really good!
Why you should visit it
It's an underground -and maybe a little underlit- place near the Ciutadella park, one of the biggest of the city. It's quite little, so I would recommend go there early to be able to eat. Also, they have shared tables in case they are really busy. It's not really expensive, and the ramen bowls are delicious and quite filled. Very recommended.
The banoffee. You will understand if you try it. Trust me on this (but it's really sweet, so if you don't have a sweet tooth... Don't listen to me).
