What drink do you have when you go out?

Water, unless it's a restaurant with some delicious drink from whatever culture the food is from (Thai iced tea, mango lassi, boba tea - that kinda thing) in which case, that.

Water, cappuccino, NA beer (I no longer drink).
If I go to a dinner style place for brunch, I like to get a milkshake. At this one place, I get them to add a shot of espresso.

Coffee, water, soda. The later at night, the more likely I am to have coffee. One of the many wonders of ADHD: getting mellow or sleepy from stimulants.

If I'm having food, I drink water. But if I'm hanging out with people I'll have coffee or beer.

Went to a comedy club last night and had a black Russian. Haven't had one in a long time and I drink alcohol about once every 2 months.

If I'm eating, usually just water
My choice of wine is a sparkling white, if it's available and doesn't clash with the food

Usually water, but sometimes root beer. A lot of local microbreweries make their own and most of them are wonderful.

After not liking wine (other than iced wine), I had some extra after making some French onion soup and figured I might as well drink it and turns out I like it now. And I've lost my taste for sweet wines. I mean, it still tastes good but I just end up with a headache after one or two glasses from trying a tawny port. It'll probably take some experimentation to find the sweet spot (heh or not so sweet spot I guess).
It's kinda annoying with all the variety, I have a feeling I won't ever get to the point of just being able to buy one kind, so each trip to the store might be a bit of a selection dillema.

Daytime: caramel latte with oat milk and an extra shot of espresso
Evening: Dark and Stormy (dark rum and ginger beer with a lime slice)
- Lime makes ginger next level, good call

If I haven't had my daily coffee yet, then a cafe latte. If it's a decent coffee place (barista with fashionably tight jeans, arm tattoos, possibly wearing a Ramones shirt) I'll go for a piccolo. If it's a really good coffee place (barista with waxed moustache and/or ironic neck tattoos) then I'll get a macchiato.
For an evening occasion, I'll generally have a non-alcoholic cider, while debating with people around me whether that's just the same as sparkling apple juice.

In the summer, beer. Ideally an import (unless there's a good microbrewery outlet nearby) because most commercial Chinese beers are terrible. For special events, baijiu. For winter, heated rice liquor.

Filter coffee or Americano. If you mean alcohol drinks then beer - what ever is on the tap. Can't tell much difference between them.
