If Crowley is close to maudlin, then Aziraphale has tipped over the other side of it, his emotions like a tap that's had the handle snapped off. No way to get those feelings stuffed back inside, not that he particularly wants to.

He makes a soft sound of complaint when he realizes that he'll have to scoot out of the booth first, which means letting go of Crowley, but it was his idea to leave, wasn't it? Besides, there's kissing to look forward to. He had almost forgotten about that. With reluctance, he drops his hug and then slides out. He gets up and immediately has to put a hand on the wall for balance, because, oh, right, very drunk on sake right now. He sobers up just enough so that he can walk out of the restaurant with dignity, because all the miracles in the world cannot keep the restaurant staff from beaming and waving goodbye to their two new favorite customers.

(Especially the redhead. Big spender!)

Aziraphale waits for Crowley to leave the booth, then very gallantly offers his arm. He waits until they are out the door and the cool night air sobers him up a bit more before asking, "So. Your place or mine?"
