It's a huge store. However, most of the items are not very specific. If you are looking for specific items, it's would be rare to find them. Things are not cheaper unless they are on sale.

Since Bunning no longer in the city, I think Ace Mart is the best shop that you can find for all your hobbies and other things that you might need fir your house

It is a Asian grocery shop.
Mainly they have korean stuff and other asian food.
If you want to have korean spicy noodle, shin noodle, they have one and many other.
