We’ve visited Chocolatería San Ginés a few times now. They are famous for their chocolate a la taza (thick, delicious hot chocolate) and churros. They also have other drinks, like coffee and tea infusions, but the chocolate is to die for. As for food, they have porras (fried dough similar to churros) and a few different bizcochos (tea cakes). They’re open some nights until 6am.
