"Theme park" on the top floor of shopping mall were kids can pretend to be anything: fireman, pizza maker, pilot, dentist etc. Very well organised and great fun.
Place can be incredibly busy with hundreds of screaming kids running around. Try to avoid school holidays and weekends and check with the reception about number of visitors on particular day/time slot. But it will always be busy..... and noisy. No natural light, so for accompanying parents it gets to be quite claustrophobic but kids never seem to mind.
