Retrograde shouldn’t work, but it does. First, though, you’ll have to stride through the Frozen Matter ice cream shop to the walk-in cooler without being distracted by the desserts or deterred by the fact that you’re stepping into a refrigerator. Once through, you’ll find yourself in a dim room barely lit by purple lights and chock-full of mid-mod accents like doughnut-shaped lamps, horsehair bar stools and a barback straight out of 2001: A Space Odyssey. Instead of milkshakes and floats, you’ll find finely crafted cocktails. But it all comes together: Retrograde is equal parts fun, glam, off-the-rails crazy and welcoming.
