Do Animals Eat for Pleasure?

I was wondering if there were any animals that purely eat for pleasure rather than just survival. Most of them will eat more than they need to eat, but do they eat just for enjoyment? How would you tell? Do we? Do humans? Well, we've got restaurants, don't we? Yeah. I mean, animals like some things more than others, don't they? We've got quite snobby cats. That doesn't help, does it? But you know what? We know what Oliver means. All dogs. Thank you, Oliver.
