Bruichladdichs. We were the last to leave the restaurant and stayed a little past closing while discussing food and drink with the knowledgeable staff who hopefully didn't mind our questions.
Via Allegro Ristorante has to be experienced to truly appreciate the passion which has gone into it. If a restaurant could be a work of art, then this would be it. We came for the whisky but were also blown away by the food and the ambiance. Wine enthusiasts would be in heaven here too. Here's a great review of Via Allegro which delves deeper into the world-famous wine cellar.
Being that this site is dedicated to videos of whisky appearances, I edited a quick video of the interior which I think you'll enjoy. And here is the link to Via Allegro Ristorante website.
