23 Best Restuarants in Barcelona
"On the edge of Barceloneta, this elegant restaurant is all white linen service and bow-tied waiters. It’s also one of the very few arrocerías (rice restaurants) in Barcelona where you can get portions of paella, fideuà (paella-like vermicelli dish), and other rice dishes for one person; in most places it has to be for a minimum of two. Apart from rice dishes, 7 Portes specializes in dishes like chicken roasted with mushrooms and Moscatel wine, overflowing platters of steamed seafood, and grilled catch of the day."
