Depending on what type of computer (if not smartphone) you have at hand, you can probably use a search engine to find the same menu. Or ask somebody at your table. Or ask the server. Or point at somebody else's food and say you want what they're having. Or eschew the menu entirely and ask to be surprised. Chef's choice can be fun.

Or leave yeah, I think that's valid. TFA is predicated on the notion of pretty-much-lying to people by telling them you don't have a smartphone even if you do. Leaving a restaurant if you can't find a menu seems like it'd be on similar ideological footing.
