Limoncello takes the small stage at The Shag Room, the velvet-draped, candlelit lounge tucked behind a secret photo-booth door at Virgin Hotels Las Vegas. It's a free, no-cover night of live music in a room built for close listening — think curtained booths, a sunken conversation pit, and a purple shag rug setting the mood while the band plays just a few feet away. The intimate scale of the space makes for a different kind of concert experience than the big Vegas stages, with the retro-glam, Studio 54-meets-Morocco décor adding its own flavor to the evening.
