It is just ok
Those favourite dishes, drinks, or media: When we introduce them to our people, we want them to enjoy those as much if not more.
"It is just ok", is not ok.
It is a phrase akin to "that is interesting". It is devoid of feeling and information.
Next you are being introduced and asked to have an opinion: Have the courage to say "I do not like this".
That is honest and kind.
