Freshness Burger operates in the basement of Sapporo Factory, serving hamburgers, french fries, and onion rings. It uses 100% beef patties and whole Hokkaido potatoes, and cooks Classic Burger and Teriyaki Burger to order. The buns contain pumpkin, which gives them a natural sweetness, and a self-service bar offers seasonings such as curry powder, hot sauce, and garlic oil. Staff respond with smiles and courtesy.
