No. It might be an undue administrative or financial burden for a restaurant to print a new Braille menu every time they change an item or price.
However, it is not appropriate for a request for a Braille menu to be answered with simply “we don’t have any.” Restaurant staff should be trained on how to properly provide the information from the menu to guests so they can make their choices from the full menu.
Public entities and private businesses have responsibilities under the ADA to furnish appropriate auxiliary aids and services where necessary to ensure effective communication with individuals with disabilities. Description of visually presented materials is considered an auxiliary aid or service.
Material in an accessible format, such as Braille, is an example of an auxiliary aid that can be provided on an as-needed basis. However, knowing your audience is key.
Promotional and registration materials for the seminar should include and explain how the public may request a particular auxiliary aid or service. This information should include contact information and a deadline for requesting individualized accommodations to ensure there is enough time to order or produce the Braille materials.
