There aren't that many Seattle reading series that have been consistently entertaining for five straight years. Cheap Wine & Poetry, which is celebrating its fifth anniversary tonight, might be the only one left. Part of CW&P's allure is its tendency to showcase only the best readers in town—tonight's entertainment includes Ryan Boudinot and Nicole Hardy, who never fails to give an enthralling, sexy performance—but at least 50 percent of the credit belongs to the copious amounts of wine, which is now and has always been just one damn dollar a glass.
