Sweet Action Ice Cream
“The freezer door at the back isn’t a freezer.”
A beloved Denver scoop shop churning small-batch flavors that lean gleefully strange — Stranahan’s Colorado whiskey brickle, burnt-honey sesame toffee, salted golden Oreo — with a deep vegan bench and pint labels designed by local artists. The Uptown counter scoops gloriously late, well past midnight on weekends. And it keeps a secret: the unmarked walk-in freezer door at the back opens onto Retrograde, a space-themed cocktail lounge hidden behind the cones.
The story
On East 19th Avenue in Uptown, what looks like a straightforward neighborhood ice cream shop is pulling double duty. Sweet Action churns small-batch scoops with zero interest in predictable flavors. On any given night, the board features Stranahan’s Colorado whiskey brickle, burnt-honey sesame toffee, and salted golden Oreo, alongside a deep bench of vegan options built on real plant and coconut bases. Even the pint containers double as miniature galleries, wrapped in labels designed by local Denver artists.
The real plot twist, however, lives past the ice cream counter. Toward the back of the shop stands an unmarked metal walk-in freezer door. Flip the toggle switch mounted on the wall beside the door frame, and a signal light alerts the host inside. When the heavy steel door swings open, you don't enter a cold storage locker—you step straight into Retrograde, an intimate, space-themed cocktail lounge tucked completely out of sight.
It makes for a bizarre, low-key scene: half the room is full of people ordering waffle cones well past midnight, while a steady stream of folks in the know vanish through a walk-in freezer into a cosmic drinking lair. You didn't hear it from us, but showing up early lets you build a flight of offbeat scoops before slipping into the back room for drinks before the late-night crowd arrives.
What it's like
Walking into the Uptown shop on E 19th Ave, you'll see a mix of ice cream lovers at the counter and people keeping a side-eye on the back wall. The board shifts constantly, so order a flight if you want to sample the stranger offerings like whiskey brickle or burnt-honey sesame toffee before committing. If Retrograde is your actual destination, head to the back freezer door, flip the light switch beside the frame, and wait for the host to let you in. Space inside the speakeasy is tight, parties are capped at five, and reservations don't exist—so get there early on weekends or prepare to wait out front with a late-night pint.
The move: Build a flight of the weirdest flavors on the board — whiskey brickle, anyone? — then, if you know the trick, slip through the freezer door into Retrograde for a cosmic cocktail.
