O Bar has now closed, and Nikki Bar will operate in its location.

O Bar is located in Pattaya's Soi 6, near the entrance from Second Road, and adjacent to Love Missile Bar.

O Bar's layout differs from other shops in Soi 6, with very few seats in front of the shop. The main seating is in the air-conditioned lounge area behind the door. The number of girls in the bar is not large, and their quality varies considerably. The age range is wide, including young girls, mature women, and a few heavyweights.
