Meal Hours in Spain

"In Spain, breakfast, or desayuno, is eaten twice. The first is a light meal, often toasted bread with butter and jam and cafe con leche (milky coffee). A more substantial breakfast follows between 10 and 11 am, perhaps in a cafe: a bocadillo or mollete (a sandwich or muffin) with ham, sausage or cheese; a thick slice of totilla de patatas (potato omelette); or a suizo or tota de aceite (sweet rolls). Churros (fried dough strips) are sold mainly from stalls.

By 1 pm some people will have stopped in a bar for a beer or wine with tapas. By 2 or 2:30 pm offices and business close for al-muerzo (lunch), the main meal of the day, eaten between 2 and 3 pm, followed by a siesta. By 5:50 or 6 pm cafes, salones de te (tea rooms) and pastelerias (pastry shops) fill up for la merienda (tea): pastries, cakes and sandwiches with coffee, tea or juice. By 8:30 p.m. tapas bars are becoming busy. La cena (supper) is eaten from about 9 pm. In summer people eat as late as midnight.

Spaniards tend to lunch out on weekdays and dine out at weekends. Sunday lunch is usually a family affair."
