人のお金で食べるご飯が1番おいしいって英語でなんて言うの？

To buy something with money can also be called to 'pay' so if you don't pay then you would say 'someone else is paying' or 'when someone else pays' The food tastes better describes what you are thinking

"Food is more enjoyable when someone else is treating you to it" tells us clearly that you enjoy food when it is paid for by someone else. Being "treated" to food is when someone else covers or pays for the bill. "I enjoy eating out. Even more so when someone else pays the bill." "Eating out" or "dining out" refers to the act of eating in a restaurant or similar and having someone else pay for the bill makes "eating out" more fun. "Free food tastes better" is a simple and cheeky alternative to the above example sentences.

There are a few ways to describe how something tastes. "Food tastes better..." is a way of saying that one way is preferred over the other. "Food always tastes good..."is a way of saying that every single time, it tastes good. "Food tastes best..." means it's number 1, at the top of the list. To explain that someone else is paying the bill, you could say "...when you're not paying". This is a pretty basic way of saying that someone else, not specified, is paying. "...When you're not the one paying"and "...when someone else is paying" are other alternatives.

If you want to explain that food tastes better when someone else is paying the bill, you can say: "When someone else pays the bill, the food is always tastier." "The food tastes better when someone else is paying."

With this statement, you are insinuating that you are able to enjoy your food more because someone else is paying for it. Thus, saving you the expense of having to pay for your own food. This statement "tastes the best/tastes better" is not to be taken literal as the food itself did not change in flavor or taste just because someone paid for it.

When expressing that food you're not paying for tastes great, you can use the sentences above to help you. Somehow we enjoy free meals more than meals we pay for ourselves. It is more of a treat and we are delighted. For some reason: a reason unknown to me Delighted: very happy Footing the bill: taking responsibility for the bill "Knowing I'm not paying for this meal makes it taste even more delicious!" "Thanks for paying for this meal, it tasted even better knowing I wasn't paying."

You want to say something like "Food tastes best when someone is treating you to it/paying the bill for you". Above are a a few example statememts which may fit this scenario. A 'freeloader' is someone who takes advantage of another person's generosity. The third example would be said as a joke - as nobody would openly admit to being a freeloader as this word has a negative connotation.

Food tastes better when it's free!' This is a common saying that expresses that a meal will taste better when you are not paying for it. Ofcourse, it will not physically taste better, but you will feel better eating it knowing that someone else is paying for it and you are saving money!
