Here is what I have in my mind when I give marks out of 10:

10/10 Naturally this has to be the perfect score. Celestial choirs sing in surround sound while spotlights bathe it in a golden glow etc etc. Can't imagine how it could be improved.
9/10 Almost there. Wonderful in all aspects, but doesn't quite have what it takes for 10/10.
8/10 Memorable, would definitely buy again.
7/10 This is the point at which I would recommend it to others.
6/10 "Nice." With all the ambiguity and lack of any other recommendation that accompanies that adjective. Nothing seriously wrong with it.
5/10 No strong feelings either way.
4/10 Some good qualities but not enough to make up for poorer aspects.
3/10 Might have it out of politeness if someone else offered it to me. Would not buy it again.
2/10 One portion can be finished, with difficulty.
1/10 Revolting. Tried a tiny bit and left the rest.
