If he's in a টক mood, some type of whiskey. তিক্ত and strong. Can be mixed with other drinks অথবা just poured over the rocks.
If he's in a flirty, happy mood, I think he's like some আরো "fruity" drinks. Just enough alcohol to get buzzed, but not enough to really taste অথবা get drunk off of.
And the rest, I think he'd enjoy a nice, hot, strong (and heavily sugared) coffee XD
