Go downstairs. That is the important bit. This place originally made the list because of a mushroom burger years ago; the burger has gone, but the stone vaults and ridiculous whisky selection have not.
Excellent June evening choice: cool stone vaults, no midday sun, and a proper place to linger over dinner or whisky.
Fine with Daniel, but this is primarily an adult food-and-drink recommendation.
Gluten-free options are advertised, but the current menu does not give detailed allergen labelling. If the gluten-free requirement is coeliac-level, ask the restaurant directly about preparation and cross-contamination.
