That is fine provided that there is an exception mechanism
30£ with the exception of London itself is tolerable if you can eat anything. If you have dietary requirements on health grounds like diabetes, allergies, etc things get interesting as you cannot just eat anything.
You definitely cannot walk into any McDonalds and have some McFood any more (unless you want to end up in a morgue).
This is the reason why I put this up-front as a requirement before we even start talking about a job. No health based exception to per-diem, well sorry no deal.
