[ Minato nods his thanks. Waitresses catch a lot of gossip, as they're always checking on their customers and having that job would put Haruhi in a good position to get to know if the princess had a favored waitress, if the one who'd served her the last time she was here had heard anything from the princess herself what had brought her mood down. There are a lot of opportunities to learn, and covering all their bases is definitely the best. ]

A seaweed salad sounds good. With... uh... underwater sesame seeds, or whatever you put in it. [ HE'S TRUSTING YOU TO MAKE IT GOOD, HARUHI... especially seeing as he's paying for the meal and it might as well be something to fuel him through the rest of the day. ]

And maybe after the meal, I could go back to the kitchen and pay compliments to the chef?

[ aka meet up and discuss whatever, if anything, they've found out through eavesdropping on the patrons in the restaurant today. ]
