Thanks for the share! Regarding the translation note at page 11, the sign reads biiru not baru, so it means draft beer (see http://nihongo.monash.edu/cgi-bin/wwwjdic?1MUJ%E7%94%9F%E3%83%93%E3%83%BC%E3%83%AB )
Also, for the gauge at pages 21-22, the legend reads "shyness gauge", with levels marked as pfft / embarrassing / too embarrassing / no way / dead .
