There is brand new "upclass" TFC joint we heard it in One City and decided not to try it out immediately. For non regulars of One City Mall, we highly recommend you park your card at the valet (or anywhere nearby) near Maybank as the underground parking is way too big to maneuver and finding the right elevator is nearly impossible. Try to get too the elevator nearest to facing the rear of Maybank (whcih is back to back with a mamak) via the side entrance to the mall and you should be very near. However the side entrance is only opened during mall hours.
The joint is located in the 4th floor and you will find the big entrance with a few well dressed security guys. The place is so big there are segregated 3 area(s). The 3 segments are open pub, TFC and karaoke rooms.
