buffet

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for buffet that I've seen before include "Refreshment - strike" , "Light refreshments - strike" , "Bang - refreshment counter" , "Batter - help yourself meal" , "Variety of restaurant" .)
