401 Nightclub offers an awesome music selection and a great overall vibe, with DJs playing a good mix of genres, including rap and 90s nights. The ambiance is frequently described as good, with personnel noted as being super nice and friendly. However, significant and repeated complaints focus on the condition of the dance floor, which is described as sticky, nasty, uneven, and difficult to walk or dance on. The drinks are considered pricey and served in tiny plastic cups. While many enjoy the music and atmosphere, there are strong suggestions for the business to invest in repairing the floor and to ensure the DJs play popular, current songs that keep people dancing, particularly on Latin nights. The consensus is that with some key improvements, the venue could fully meet its potential.
