Mezcal Lab, before being ushered down to the smart basement restaurant below. It soon becomes clear that you're not in any old Mexican place. For a start, the service is excellent, at a Michelin star level I'd say. After a lovely little appetiser (a sign of things to come), they theatrically mixed Guacamole at our table with a pestle and mortar (€4 per person). It was the most beautiful guacamole I've ever eaten. I think it may have spoiled all future guacamole though. The tortilla chips also were quite different from any we'd had before.
David Muñoz is a fan of this place, and it was to his restaurants where we would venture next on our Spanish journey.
