I think the ADA might apply here. Domino's lost an ADA lawsuit because their online ordering wasn't accessible. Disability is also a protected class here, but I'm not sure if or to what degree that would mean anything. Afaik you can't refuse to serve a protected class at a public establishment, but I don't know if that compels them to make modifications to the business or not.
