"It is like a slushy. It's made like one. I think, at least. With ice and flavoring. It's just that they put something else in it that makes it look like that. I'm really not sure, but it's good, I promise." Sulu took a drink of his own to prove it, because really, it was good. He liked them well enough, even if he usually got a soda. It was worth it to give Ianto a taste of something from this era, he figured.

"And anyway, if you want anything else, man, you just have to ask. It's not like it's a big deal to me if you want vinegar or... I dunno, you don't like the Slusho and want a soda instead. I'm not going to blame you for being sort of shy here. It is a different time, and all."
