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 townโ€”tonight’s entertainment includes Ryan Boudinot and Nicole Hardy, who never fails to give an enthralling, sexy performanceโ€”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.
