Christmas-heads, prepare yourselves for the coming of more than a half-dozen holiday-themed bars this season around Denver — and another in Colorado Springs, just in case you find the local options lacking. Starting on Thursday and continuing until the New Year, you’ll have your pick of pop-up bars. Fans of the European Christmas market tradition can even head to a new outdoor plaza bar coming to Union Station. For the most over-the-top Christmas experience, check out the Denver Center for the Performing Arts’ Camp Christmas installation and Santa Bar at Stanley Marketplace in Aurora. Or for a holiday drink with views, there will be rooftop holiday parties with alcohol served from a decked-out Airstream at the new Edgewater Public Market. Four Miracle Bars will vomit Christmas decor — and cheer, but hopefully not alcohol — all over Colorado this year, from Larimer Square to Highland, Arvada and down to Colorado Springs.
