Madam Chen has 2 karaoke rooms. The small karaoke room is suitable for about 10 people and the large karaoke room is big enough for 20 people. You can use both karaoke rooms for free for 3 hours, but it is the intention that you spend a minimum amount on food and drinks. The minimum spend is 250 euros for the small karaoke room and 350 euros for the large one. So you cannot bring your own food and drinks
