Pasteur Milk Bar is an ice cream shop in Lotte Department Store Gwangbok Branch in Busan. It serves milk ice cream and milkshakes, along with milkshakes with a strong milk flavor, ice cream lattes, and Greek yogurt. Milkshakes appear in visit records from 2017 and 2025, showing the menu has continued for a long time. Because it is inside the department store, it is crowded and hard to drink comfortably.
