Coffee is not the optimal first date, I prefer walks as it's easier to be physical.

But going for a coffee is not a bad option for an instant date during the day.

Here's how my last instant date at a mall was initiated:

Me: I have 10 minutes, let's go for a coffee over there
I start walking to the direction of the coffeeshop 20 meters away.
Her: I don't drink coffee this late... but tea is fine

At the counter:

Me: What do you have usually?
Her: Tea
...
Me: 2 green teas

Note that I didn't make a big deal out of which beverage or which variety of tea she'd like.
