I remember in my youth walking into each club or bar, and finding the prettiest woman in the place, then going up to her to strike up an convo, have a drink, or ask for dance. It was great practice. First, it allowed all the other women to see that if she did so, I might have something to offer them. Second, it was likely that most if not all of the other guys didn't have the balls to do the same, so my chances were better than one might expect.
You going up to your wife first, but with an air of mysterious confidence will be fun, light, and will communicate this appreciation of her. Thats all that matters, Wes. She'll remember that later. Be fine drinking alone. Flirt w/ the bartender (if female! ), chatter with those around you, and celebrate life, this country's birth, you name it. She will be watching you.
Contact her, wander away for a bit, but always keep her at the center of your focus, your circumference at the place. She and her GFs won't be in charge, with you confidently moving about, expressing your masculinity. Sounds cheesy, but those are the true dynamics, my friend.
