Still haven’t managed to wrangle yourself a floor pass for the Pepsi Center? Then the next best place for celebrity spotting is turning out to be Jesse Morreale’s Rockbar, renamed Barackbar for the festivities. (It’s located at 3015 East Colfax Avenue, on the ground floor of the All-Inn Hotel). Last night’s post-convention shindig attracted plenty of Denver’s temporary beautiful people: Alan Cumming, Susan Sarandon, Josh Lucas (who seriously knows how to close a bar), our own Holly Kylberg and Morreale himself, who spent a good portion of the night buttonholing Lucas about a proposed partnership on a bar/restaurant/celebrity retreat in either (depending on the time of night) Denver, Los Angeles or Mexico. When he wasn’t doing that, he was being the good host, introducing everyone to everyone else and, most of the time, even getting the names right.
