Pastakudasai Voiced !!top!! -

This phonetic smoothing mirrors a sociological smoothing. The word pasta itself is a gairaigo (foreign loanword) associated with cosmopolitanism, youth, and casual dining. Unlike the formality of traditional Japanese cuisine (e.g., soba o kudasai ), ordering pasta carries an inherent relaxation. You would not typically voice a request for gohan (rice) into a single breathy unit in a formal setting. But in a famiresu (family restaurant) like Saizeriya or Jiro, pastakudasai rolls off the tongue with the ease of a friend asking for the salt. The voiced continuity signals familiarity: the speaker is comfortable enough with the server and the environment to blur the rigid boundaries of standard request grammar.
