That St. Mark's Coffeehouse is a great place to stop for a cup of joe should not come as a surprise to anyone. This offshoot of the original LoDo spot has drawn the hiptelligentsia since first opening its enormous sliding garage door in 1997. They come for the coffee, bagels, panini and sweets, but stay for the company: cool teachers grading papers, the students who wrote them, artists and journalers, businessmen and housewives, and, of course, those insufferable coffee-shop rats, smoking hand-rolled cigarettes and reveling in their own asinine chatter. St. Mark's has always been a good coffeehouse, but it's gotten even better over the past year. It ditched the fee for wireless and opened up the Ubisububi Room, a performance area that shares basement space with the Thin Man next door and offers everything from free movies to standup comedy to live acoustic music. The Thin Man and St. Mark's share ownership as well, and a swinging-door relationship allows 21-and-up patrons to enjoy a cocktail on either side of the common wall. So grab a mocha or a mojito, and settle in to enjoy the Paris of the Plains version of cafe culture.
