One of our favorite activities while in Spain was enjoying tapas. Tapas (derived from the Spanish verb tapar "to cover") is the name given to a wide variety of appetizers in Spanish cuisine. In Spain dinner is usually served quite late - between 9-11pm. This leaves alot of time between work and dinner. To fill this gap Spaniards often go to a bar or restaurant and eat tapas.
Bars and restaurant typically have a dozen or so different kinds of tapas on display. Ordering tapas takes some getting used to as it is self serve - just go up to the counter and get it - and the bill is derived at the end from counting the number of toothpicks on your plate. Once we got the hang of it, sampling tapas became a regular part of our daily routine.
