The most crowded place here at OneCity is probably the NSK hypermarket. Most people come here to do grocery shopping and get their essentials. No doubt it is a preferred place to do the shopping because there are plenty of indoor parking spaces, unlike certain hypermarkets which are difficult to get parking after 10/11am.
NSK OneCity is a huge hypermarket where you can buy just a single unit of product or in bulk at very affordable prices. It offers much more than Lotuss or Giant hypermarket, but the condition is almost like a big wet market (especially in the area selling fish/meat/vege) where the smells are quite strong.
The mall itself is pretty empty without many shops still in operation. At a glance, one can tell that it is in an abandoned state.
The sky park gives you beautiful scenery from the top of the building. There is a restaurant and bar up here but all were closed, perhaps they open in the evening time.
