It means, 'A bit of advice to you"

“Word to the wise” is a shortened version of the phrase “a word to the wise is sufficient”. It can kind of mean different things, but basically it suggests that if you’re smart, you’ll listen when you’re given advice about something. “Quite the scene” can also mean many different things. It often suggests that a place or event might be very busy, or loud. It can also sometimes be used to describe an unpleasant situation such as a fight or a crime scene. For example, you could say “they made quite a scene when they had a fight in the middle of the restaurant”.
