The gastrobar ULTRAMARINOS QUINTIN has the best location in Madrid: in the edge of the neighbourhood of Salamanca.
It will delight you with the amazing atmosphere (but be aware sometimes too busy).
Take a moment to appreciate the draft tap, the take home bread, the grocery shelter, the cheese corner… Just a perfect place to repeat for a drink, or a tea….or for a lunch or dinner if you don’t mind a crowded feel. Food is correct but not as excellent as their below partners:
EL PARAGUAS & TEN CON TEN.
