Does a guest incur an upcharge for French fries instead of hashbrowns with an omelet?

When a guest orders an omelet at Denny's, substituting French fries for hashbrowns does not incur an upcharge. This policy is designed to provide flexibility in meal customization without creating an additional cost barrier for the guest. It's common in many dining establishments to allow simple substitutions like this to enhance the dining experience and accommodate guest preferences.

The concept of upcharges typically applies to premium items or significant changes to a meal that involve higher-cost ingredients, but in this case, both hashbrowns and French fries serve as standard side options, making the substitution seamless. Thus, the guest can enjoy their meal without worrying about unexpected costs for opting for one standard side over another.
