Zoro doesn't startle easily, but for a half-second he's absolutely shocked to hear his name in this strange new place. He would think he's under attack if he doesn't also recognize that very distinctive bellow, nevermind the unmistakeable vice grip of a signature Luffy hug, complete with the threat of suffocation. "Luffy," he says, cheeks red and flustered from some of the attention they're drawing - he'd wanted to be incognito, or at least as incognito as he could be while silently picking randos to interrogate.

This is better, though. Luffy's here, and maybe he has some intel. Zoro clears his throat, straightening out his suit, briefly distracted by seeing his captain in something besides his usual casual attire. "I can't believe you're here, too. I thought I was the only one..." He shakes his head, briefly glancing at the buffet tables all around. "You've been eating here? And you've been fine?" His eyes narrow suspiciously. This is the guy who downed a whole pot of blue, poisoned soup, after all. He's not sure he can trust his judgement about food safety.

Zoro looks surprised at the mention of their chef. "Sanji's here, too?" That's good. Very good. Not that he loves the guy, but the presence of another ally gives them a better chance of escaping. He takes Luffy by the elbow and guides him into (what he thinks is) a secluded corner so as not to be overheard. "What is this place, do you know? Who brought us here?"
