The Dream Mall building has a shape of a whale and on its roof there's a Sanrio ferris wheel. Other than the shapely architecture and what may pass for the "Kaohsiung Eye", the place is no different from other super malls with stores that sell all possible merchandise (clothes, shoes, furniture, accessories, houseware, etc.). The basement has a supermarket and food court.
nothing much special, just that you can find its branches easily.
Try not to buy at the airport because they are always more expensive than others branches ourside the airport.
What to buy: dried beef, dried pork, plum jelly, shredded dried squid, etc
What to pay: really depends on your taste, i like eating and i like their food alot, but i only spent about NTD 1,500 to buy food in the trip. They are pretty cheap
