Slaughter buffet

Seen in a hotel/restaurant near Nürnberg, Germany.
Literally translated the sign says: "Slaughter buffet, eat until you burst for  € 6,80"  ($ 8.56).
I guess the word slaughter doesn't bring up many positive feelings in most cultures, but the pig and the cow on the sign look very happy. According to the restaurant's menu, the buffet consists of; bratwurst, liverwurst, blood sausage, boiled pig's stomach, soup and for the few vegetarians over there they also offer; sauerkraut, potatoes and potato salad.
