Long overdue, but having been to Barcelona a number of times, I have been wanting to write some of the secret parts of the city that I encountered, and that are worth seeing. It's worth citing that a lot of the restaurants were originally gotten from an amazing list of restaurants my doctoral advisor shared with me, and that a lot of the places I love going to were first shown to me by our program director, who knows Barcelona better than anybody I know. Additional note : Barcelona runs on a different time schedule than other countries. Dinner at 9-10pm is very common, and people start going out around midnight (to bars). Clubs start around 2am and go until about 6am, so keep that in mind as you enjoy the city. They also have afternoon naps (siestas), so in the early afternoon, a lot of things may be closed. The summer is usually pretty packed regardless because its booming with tourists. I generally do not like crowded toursit-filled areas, but you have to experience them once....
If I feel like writing about something that happened in my day, it will happen here :). Enjoy.
