It is crucial to first gain a thorough understanding of the range of dietary restrictions and how to cater to customers with these special preferences. Review your menu to gain a deeper understanding of how your offerings match up to the current customer base you’re catering to. You might be surprised with the number of offerings that are already in line with certain diets. Highlight these menu items with common dietary requirement icons for easy viewing on the customer’s part.
There is also the option of introducing an ingredient substitution method that replaces allergens with allergen-free ingredients. For example, a customer with a dairy intolerance would opt to leave out cheese, or a customer with a shellfish allergy would want to swap shrimp with chicken.
