It’s just about fall, which means we’re all on the clock for drinking-on-the-patio season. If that’s you, head to the top of the Le Meridien hotel while you can. That’s where 54thirty, Denver’s tallest open-air rooftop bar, just opened on Sept. 14. Perched on the 20th floor, 54thirty offers great city and mountain views to go along with its fun cocktail menu.
