Tipping
In most restaurants in Buenos Aires a 10% tip is the norm. If the service was superb, 15% is appreciated. In bars you can tip a peso or two per drink, but it's not expected. Bills for parties of six or more sometimes include the tip; look at the check. Many restaurants also charge a servicio de mesa (table service) or cubierto, which typically runs anywhere from 10 to 50 pesos per person, and covers the cost of "breakage and replacement." It is the source of much local contention—those who don’t charge it often make it a selling point. If there is a table charge, many locals tip less, though it should be noted that the cubierto does not go to the waiters but to the restaurant’s owner.
