Vaultaire is a basement hi-fi cocktail bar under La Foret on South Broadway. The format is compact and low-lit: analog sound, vintage spirits, French-leaning bites and a room designed for records to sit close to the drinks. The focus is simple: analog sound, vintage spirits, French bites. That gives the place a clearer listening-bar identity than a standard cocktail basement. Best for a seated Denver cocktail night with music treated as part of the bar's character rather than decoration.
