Ametsa with Arzak Instruction

I thought part of the reason why our lunch at Dinner by Heston didn't fare as much as the hype was because it's overshadowed by our lunch at Ametsa the day before. Similar to Dinner which was backed by a chef who owned a Michelin 3-starred restaurant, behind Ametsa was Juan Mari and Elena Arzak, who owned the 3-starred Arzak in San Sebastian in the Basque Country (of Spain), which we had a chance to visit a few years back. This London outpost of theirs was rated as one-star in its own right in the latest Michelin guide.
