Scoring

I'm not so keen on scoring, although it is a useful quick glance item.

Perhaps, as a reference, it is useful to know food is the most important aspect for me although setting and service do have a bearing.

Food will get a

Would go back. Regularly.
Would go back, but not regularly
Would not go back unless someone else is paying
Would not go back

I guess that means

"Would go back. Regularly." is grade A
"Would go back, but not regularly" is grade B
"Would not go back unless someone else is paying" is grade C
"Would not go back" is D or below

These may be qualified by (If I could afford it) if there's a big value concern.

Any thoughts on a better scoring system?
