Located literally underground - patrons have to walk down two flights of stairs to reach the entrance - the place has a bomb shelter vibe: Concrete and metal are the main elements here, excluding the wall made of wood panels, and the lights have a green-tinge to them. Low gray and khaki leather couches are spread throughout the space and provide the perfect camouflage for the bar staff sporting army-inspired mini-dresses and fatigues. Flat screens playing snowy black and white images intimate hijacked video feed, and even the napkins exhibit Underground's bomb shelter logo. Lost fanatics would have a field day here.
