Here's a rundown of Spanish eating customs. It's quite different from other countries - mainly because everything happens a couple of hours later! Don't expect to dine before 8:30pm, and don't expect to eat lunch at noon either...

Breakfast/ El Desayuno

• The least important meal of the day... some Spaniards skip it entirely!
• Time frame: sometime before 10am
• Usually "continental," consisting of coffee, juice, hot chocolate or tea + a croissant, toast with butter & jelly, toast with olive & tomato, any other kind of pastry, or even a pincho de tortilla - a slice of a Spanish omlette.

Coffee/ El Café

• After 1 or 2 hours at the office, it's typical for co-workers to step out to the local cafetería for a coffee.
• Time Frame: between 10:30 and noon
• Café solo (Spanish)/ Cafè sol (Catalan): a shot of espresso
• Café cortado/ Cafè tallat: a shot of espresso with a little bit of milk
• Café con leche/ Cafè amb llet: a shot of espresso with a lot of milk (like a latte)
• Café americano/ Cafè americà: watered down coffee, American style
  

Lunch/ La comida

• By far the largest and most important meal of the day
• Time Frame: sometime between 2pm and 4pm
• This is the time of day to find great cheap deals at otherwise expensive restaurants.
• Most places have a "menú del día," a prix fixe menu allowing you to choose from various options for 1 appetizer and 1 main course. Usually includes dessert and a beverage as well. Prices range between €7-€11.

Afternoon Snack/ La merienda

• Since Spaniards eat dinner so late, some may have a light afternoon snack to hold them over.
• Typically a pastry, hot drink, or small sandwich
• In Barcelona, pa amb tomàquet is a typical merienda

Dinner/ La cena

• This is a much lighter and later meal than many foreigners are accustomed to. Restaurants won't open until 8pm or later.
• Time frame: 8:30pm at the very earliest. Typically 9pm-10:30pm
• While tapas culture is not very strong in Barcelona, it's still worth mentioning as a local dinner option. A tapa is basically a small portion of food, meant for sharing. There are all kinds of tapas: cheese, cured ham, croquettes, anchovies, potatos with ali-oli or spicy sauce...
• The culture of tapeo is highly social. Typically, a group of friends will hop from bar to bar, eating a couple plates at each destination and drinking beer or wine along the way.
• Tapas are usually eaten standing up!
