Jacqueline in Bangbae
This is a fantastic pool hall with 10 full sized pool tables as well as some three cushion tables for those interested. They have 11,000won special days on Monday and Thursday where you can play or practice all day for that price. On those days it can get quite busy, so you may have to write your name on the board if you want to take part in the special day price. If you want to play and pay normally for time, they will direct you to a table you can use. Joo Chan Kim is the owner/manager and is very friendly.
Go out exit 3 at Bangbae station line 2. Walk 3 minutes and you will see Jacqueline on your left in the basement floor.
