Dart places are commonplace in Hong Kong. Unlike Singapore, where playing darts for a night out is virtually unheard of, in Hong Kong, its like drinking water. Perhaps, from the influence of the English in Hong Kong.
The dart boards are electronic and records scores of players.
These places also serve alcoholic drinks and juices and tea. Its a pub like atmosphere.
If you are keen on doing something different instead of the usual pubs. Perhaps you might enjoy playing darts.
Address: Bartlock Centre, level 22, Causeway Bay MTR Exit A, exit from Times Square via Ferragamo at Central Entrance, turn left, walk along Matheson Street, turn into Yiu Wa Street located on the second light lane. (its a bit tricky so I advise to use google maps for this)
