twelve o'clock
`` Adolphe retired and sought the _ patron _ , and Dupont advanced to her with dignity . '' ` Madame is plainly ignorant of our arrangements , ' he began ; ` at twelve o'clock one can not remain here for the cost of a bock -- the restaurant becomes very gay , ' '' ` So I believe , ' she said ; ` I want to see the gaiety , ' '' ` It also becomes expensive . I will explain . During the evening we serve a dinner at two francs for our clients in the neighbourhood -- and until twelve o'clock one may order bocks , or what one wishes , at strictly moderate prices . But at twelve o'clock there is a change ; we have quite a different class of trade . The world that amuses itself arrives here to sup and to dance . As a supper-house , the Bori Vieux Temps is known to all Paris . ' ''
