[Yikes, he really does have a way of looking at you like he's going to crush you no matter how much shorter than you he is. Yuuri stammers for a second, but pulls himself together, because really, letting him drink that other cocktail seems like a fast track to spending the rest of his night holding a teenager's hair back for him while he throws up...]

I thought... um... maybe a chuhai? If you don't like the way the liqueurs in that one tasted, especially all mixed together... It's got shochu in it, that's like Japanese vodka, but it's mixed so you don't taste the alcohol very much, and shochu doesn't have much flavor of its own besides "alcohol" so it mostly just tastes like a normal drink?

[And if he can talk to the bartender himself, he can be sure it's mixed light, so it'll be more or less as alcoholic as a light beer, but still technically not going the "here kiddo, have a soda instead" route...]
