The cloisters around Plaza Nueva are home to many shops and businesses that have changed little over the years. The casco viejo vies with the parte vieja in San Sebastian as the gastronomic epicentre of Spain and here was born the practise of 'txikito' , the ultimate bar crawl. A group of friends move from bar to bar, taking a small glass of wine or beer at each - a txikito or chiquito - combined with a few mouthfuls of pintxos, the Basque equivalent of tapas. Victor Montes, pictured above, is one of the best places to experience this.
