Studiodanz

This should be a very familiar name to the dancing community in Hong Kong; more likely still, you might have taken classes in here if you ever danced~
One of the leading dance institutes in Hong Kong, Studiodanz (SD) was established in year 2003 by Angela Hang and Yvette Nie. Offering a wide rage of dance styles from the more popular Hip Hop and Jazz funk to contemporary and Ballroom, SD believes that dancing is for everyone and anyone can dance.
Located in an industrial building in Fortress Hill, a large space is reserved for the 2 dance studios for dance classes to take place. Normal dance classes hold around 20 or so people whereas during big events such as dance festival, in which renowned tutors and dancer abroad are invited to give classes in HK, the rooms could pack up to 50 people!
Earlier classes start at 17:30 where as most classes start 19:00 and 20:30 catering to the working population, SD would be your another option other than hitting the gym and lifting dumbbells. The energetic dance moves not only will make you sweat, but will make you a star on the dance floor as well~
Just a side note, the couches outside of the studios are quite ideal for a quick nap and indeed many students often do too before the classes start; but if manners are in concern, I would suggest not to do so.
