i agree with 196.
we do have lots of words osusume/susume.

but my guess as to osusume is probably 'recomendation' or 'suggestion' might be close to what you want to know.

like, in a sushi restaurant,
kyou no osusume wa nandesuka?
-> What is today's special?/What do you reccomend today?

kyou wa maguro ga osusume desu.
-> I'd recomend some tuna fish./we have good tuna today.
