Lonely Planet 2011 Spain Guidebook
"San Sebastian Food has an array of pintxo tasting tours and cookery courses in and around the city."
"San Sebastian Food is an excellent English-speaking set-up that offers various gourmet options from pintxo tours of the old town – a good way to get the hang of this sometimes intimidating way of eating – pintxo cookery classes, wine tastings, Rioja visits and more. You can book online. Recommended."
