Zoro notices Shanks before Shanks notices him. He watches, a little impressed, as Shanks catches an arrow. The way the older man seems to be having the time of his life amidst the chaos of the game strongly reminds him of Luffy. He laughs, shaking his head, and spends a few minutes dodging arrows and knocking out cherubs before he hears his name.

He sees the lifted mug and nods back in acknowledgement, then promptly does some unnecessary combo of backflip-duck-slide to evade a shot from Cupid. Is he showing off? Maybe a little.

He moves closer to Shanks, nodding at him. "You should go in there," he gestures at the lines of telephone booths. "I think people go in there to take breaks. Have your drink in peace. Or jump into one of these, but I don't know where it goes." He gestures at a hole in the wall that seems to be a slide leading somewhere dark and unknown.
