Experience the Autumn Flavor Revolution with Freshness Burger's New Mushroom Cheese Burgers!

Embrace Autumn with Freshness Burger’s New Offerings

As the autumn season rolls in, Freshness Burger is back with its highly anticipated Mushroom Cheese Burgers, marking the seventh year of this seasonal delight. From September 3 to October 14, 2025, patrons can indulge in two exquisite variations of this beloved favorite: the Mushroom Cheese Burger with Porcini Cream Sauce and the Mushroom Cheese Burger with Truffle Demi-Glace Sauce.

Freshness Burger, part of the Colowide Group and headed by President Kentaro Saito, is determined to elevate the autumn dining experience. With a commitment to quality, the burgers feature juicy, domestic shiitake mushrooms that are generously grilled to perfection for just 30 seconds. This brief grilling time enhances their natural flavor, resilience, and delightful texture, making each bite a savory treat.

The Mushroom Revolution: A Symphony of Flavors

Unlike traditional season favorites, which often lead diners toward the Moon Viewing Burger, Freshness Burger is boldly declaring its allegiance to mushroom connoisseurship this year.

The spotlight shines on the delectable flavors of the world’s finest mushrooms—Italian porcini and the prestigious truffle. These ingredients not only enhance the sauces but also add depth and richness to the overall taste experience. Those seeking to savor the unique essence of these gourmet mushrooms can do so through the carefully crafted sauces, each promising a luxurious and aromatic dining affair.

What’s New This Autumn?

1. Mushroom Cheese Burger with Porcini Cream Sauce: Revamped for its seventh anniversary, this fan-favorite burger features a rich and creamy sauce boosted with white wine. The addition of finely chopped mushrooms takes it up a notch, intensifying its flavor profile.

2. Mushroom Cheese Burger with Truffle Demi-Glace Sauce: A brand-new offering for the fall of 2025, this burger presents a robust demi-glace sauce enriched with red wine and spices, elegantly finished with a hint of truffle fragrance. Diners can expect a taste that rivals even high-end restaurants.

In both variations, the showstopper remains the quarter-pound, juicy beef patty that bursts with flavor. Its rich, beefy goodness melds beautifully with the velvety red cheddar cheese, delivering an unparalleled mouthfeel that is truly satisfying.

Autum Craft Pairing—Limited Edition Refreshing Craft Lemonade

To complement the mushroom delights, customers can also treat themselves to the Craft Apple Ginger Lemonade, available in both iced and hot versions.

Each cup provides a refreshing burst of wellness and revitalization.
