Le Pain Quotidien
This French-themed chain bakery is a safe bet when it comes to Wi-Fi and its locations in Madrid are pretty spacious, so you’re likely to snag a spot at a table or on the long communal table. Food ranges from freshly-baked croissants and other pastries to a good range of vegetarian options and, of course, plenty of café au lait.
