The younger Shrike had definitely avoided diners, at least at first, instead preferring to buy his food from the stores. Though he did marvel quite a bit at first at, well, pretty much everything. At least in private. And at least once make a remark to someone about how surprised he was both at how much was available to buy and that the prices in the stores were the same for everyone.

His older self, well, at least right now he's more likely to keep any thoughts like that to himself.

"And eaten all together, I presume? Like foods served rolled in a flatbread or cooked in a dumpling?" He's definitely having to think about how that works; evidently this particular form of serving food is new to him.

He'll doubtless have many more questions once he actually finds the drinks section.
