Ordering off a menu can be tricky if you're not sure what to choose. Sometimes, a customer may want to order off the menu for special dietary needs. In such scenarios, customers may ask for substitutions or customizations, which can throw off the kitchen's usual routine. In this case, the phrase "order off the menu" could be replaced with "make a special request" or "place a customized order." Alternatively, if someone needs to leave a restaurant immediately, they might request to "order out" or "get their food to go". These phrases refer to the same idea of customizing orders to satisfy specific needs and preferences.
