Time Out says
When the terrace opens it's near impossible to find a place to sit at this most-sought-after spot in the square. The good news is they hardly ever close, so whenever the mood strikes, you can stop in for breakfast, sandwiches, snacks (from Iberian hams to basic nachos) as well as more elaborate and international options (wok dishes, moussaka...).
