@Supermouse Things they call "highball", which I thought was that you have a big floaty ball of ice in your whisky, but here it means cocktails with lots of crushed ice; could be whisky and beer, could be vodka and raspberry, or something else; and they sell it in cafes where you would have ice cream and coffee.
Also, I've had Korean beer at home, but not the rice beer I've tried here.
The soju here is mostly familiar from the Korean supermarket at home.
