We’re about to tell you to lie to your date.

No, don’t tell her you’re on the Redskins’ practice squad, or that you’re in line to be Mitt Romney’s secretary of math.

Just make a reservation at 8pm. But tell her it’s at 7:30pm.

Trust us: there’s a tree swing in it for you.

Welcome back to Dupont standby Firefly, all renovated as a heavy-on-the-cocktails, woodsy retreat, reopening Saturday.

This is the casual date spot you’ve always known, but after a three-week renovation, it’s returned as something out of a Robert Frost poem: an ivy wall, a kitchen facade that looks like a cottage and lighting designed to evoke dusk.

And oh: the tree trunk. Yep, that’s still here. Only now it’s been adorned with the aforementioned two-person swing—exactly where you’ll want to take up while you wait for your table. You won’t want to swing empty-handed, however, so be sure to bring a banjo. Or just delve into the new cocktail list for the Firefly (gin, rum, honey, pine, yuzu) and the Listen How Parrot Laughs (gin, quinquina, vermouth).

Meanwhile, on your plate: mini pot roast, deviled eggs and some new bar snacks like pimento cheese fritters and oxtail sliders.

Wait a half hour before swinging again.
