By spring, the pop-ups had taken over Denver. A Harry Potter brunch, a LEGO Bar, Magical brunch, ball pit bar, real-life Mario Kart, Miracle bar, a spring break bar and an Olympics bar. But that’s not all: A fried chicken pop-up, Pokémon pop-up, poutine pop-up, pop-up bar within a real bar, pop-up spawning another pop-up, a wine bar visiting a restaurant in a food hall pop-up (more on this later), and the nation of Iceland in Denver for one night, popping up (too late, you missed that). What started as an occasional, decked-out holiday event had become a calendar full of immersive parties and one-time-only experiences.
