The Boqueria market (a heaven for seafood lovers like us) is only a 5-min walk from Hotel 1898. The market closes on Sunday and open till 830pm on other days.
Every stall inside the market looked enticing but a couple of spots cams highly recommended by friends. One is Pinotxo but we went there at 3pm on a Monday which was the worst time to go: almost everything on the menu ran out by 3pm, and they supposedly get fresh delivery every Monday evening. We ordered one egg/prawn dish (that might have been the only dish left) and it was nothing special.
