Tommy will bitch and whine a little, but be secretly pleased by the free food. He can understand affection when it's forced on him.

"Huh. Looks like an ... okay place?"

He's never been to this restaurant before, so he stands just inside the doorway, waiting for Kate to give him his cue on what he should do to get his food. Better to do that than accidentally piss off the chef-dude-person and get his drink spit in.
