There is a popular French song, C’est si Bon which means “it’s so good”

I envision slurping from a hot bowl of onion soupe on a cold day in a French cafe. The waiter stops by to ask how I like the food

I say “C’est si Bon,” based on the song  (It’s so Good)

Here are some other French Songs which provide a French Cliche or  reference a French landmark:

Autumn Leaves “Les feuilles mortes” (literally “The Dead Leaves”)

Plus je t’embrasse (The More I Kiss You)

Je T’aime,…Moi Non Plus (“I love you – me not anymore”)
