The data limits for a QR code are rather small. Note the storage is also used by ECC payload, which generally isn't optional. https://en.wikipedia.org/wiki/QR_code#Storage

The menu is probably going to insist on using lower case letters, and the "Binary/byte" encoding will be interpreted as something between 7-bit ASCII and UTF-8 depending on the client. With the ECC payload 2,953 bytes sounds like quite a lot, THEN you look at the giant art linked in the article for even small examples. The size (version) 40 takes 177×177 width of decodable, clearly visible pixels.

At that point the QR code is in the ballpark of a printed 8.5x11 or A4 sheet of paper, and is far less useful to humans than a laser printed page with multiple sizes of lettering, super high contrast, and no requirement for a computer to decode.

Haha, yeah... I'm not sure how important it is to have ECC to menu text.. good info.
