What Nadia actually says at the very end of the episode is, "I'm looking for a cage without tigers where I can rest my bones".
Nick is about to tell Dunston the bathroom is to the left of the popcorn machine, an object that was heavily argued about between Nick and Cece in the fourth season episode "Spiderhunt". Jess thought Cece had a crush on Nick, but they were actually arguing about getting a popcorn machine for the bar.
