@bertrand-011930xl hello! There’s a dance studio called ‘Glissade’ at Bukit Merah central. It is very accessible as it is near the bus interchange, and also very affordable, and its prices are below market rate. The teacher is very amicable and approachable. This studio would be good especially if you are just starting out at ballet, but it has many students taking the advanced classes too. Even though the FB page may be quite old the studio is very well maintained. The teacher is also very experienced. Hope this helps?
