Kyeongsan Market (경산시장). 

It's not as big as the other market in Daegu (Seomun Market), but it has a variety of fruits and vegetables, clothes, sweets, side dishes, fish, meat,etc. It is also surrounded by some restaurants, cosmetic shops, marts, banks, eye glasses stores, cosmetic clinics, and so on. The products are cheaper than in supermarkets/mart and they taste better, plus you can also get some discounts.
