You walk inside the unfathomable, overbearing building to find a rather quiet lobby-- much akin as a hotel's lobby. The lobby is lit with an uncomfortable purple light emitting from a chandelier and lamps. In the middle, there's a seating arrangement and table.
Most notable is the couch that sits in the middle with its odd color and how larger it is than the other seats. Probably has been used more than the seats, for some reason..
Behind the seating area is the front desk. There's also a few elevators next to the wall, and a an open entrance to what seems to be the darker part of the hotel-slash-casino.
