Caelum

"Set among the labyrinthine streets of the Gothic Quarter, this café offers a delicious selection of cakes, tarts, cookies, and other desserts—all baked by nuns from convents and monasteries around Spain . There are truffles from the sisters of Valladolid, cider cake from Santa Inés of Seville, and tea biscuits from the Convento Madre de Dios in Cáceres. Enjoy them with a cup of coffee or pot of tea, or try the famous hot chocolate. You can get a table upstairs, but it’s down below that you’ll want to score a seat: The space—a medieval-era Jewish bathhouse—features ancient stone walls and high vaulted ceilings. Live classical music concerts are occasionally held there, making for one of the more magical places to indulge your sweet tooth."
