OK homoe was looking forward to someone else posting in this thread so here is a short list of places you must visit / things you must do if you're in Denver:
Brunch at Beatrice and Woodsley. Second best Bloody Mary in the Denver area and the dining room is filled with magical amber light and aspen trunks. (I'm going to try to post a photo, forgive me if it doesn't work.) They have big comfy booths but I also love eating breakfast at the bar because the bartenders are friendly and really fascinating to watch.
