Chocolates y Churros San Agustín is a casual, local churrería where you go for hot, freshly fried churros and thick drinking chocolate, so visit mid-morning or early evening for the best texture and shorter lines. Expect affordable prices and generous portions, bring small bills because some locations prefer cash, and plan on takeaway if seating is scarce. Keep your order simple since staff may mainly speak Spanish, and be mindful of very hot sugar and oil if you are with kids or have dietary restrictions.
