He just jumped right in the middle of Mike's question

why does he say "nine-ish". What does that mean?

Great phrases!

I think they all knows what's happening

An indirect way to ask Mike for a meal. Such a smart lady!

Is this what he's thinking or he does say it out loud?

She's just pretending. Her eyes say so

A way to suggest "private discussion" between guys

An hour?  What are you feeding this dog, cement?

She uses the definite article 'the'.  This implies that the girls know which shop she's talking about because it's the shop they always go to late at night.

Yeah, she had some eggs a la Rocco.

Nice use of the past continuous by young Mikey.
