Stone is where you go to find young company or late-night grub (or both). Cavernous (like everywhere in Matera), its brightly lit interior has been given a lounge-lizard makeover with suspended glass floors and luxuriant furnishings. The filling but largely mediocre food is secondary to the vibe.
The noise level rises as the night progresses, but there are plenty of alcoves if you wish to escape the TV soccer, loquacious DJs and out-of-town trendies clustered around the aperitif buffet.
