When you "one on one time" like closing shift or something, when you sit with him, be honest.
Ask him "do you mind if I tell you something?" then tell him you really like him and you are glad you get to work with him. Tell him he is handsome or something.
I suggest this over a question. Let whatever happens happen. You can always ask him to grab a beer together the next day or sometime later.
Dunno if it helps.
